Your Body is Your Temple

I don’t mean that in the gym-bunny, mirror-worshipping way mind you! I mean it in a biology-is-amazing way. I genuinely am proud to be a geek when it comes to biology and how amazing it is to study. I knew I wanted to be a doctor before I understood what a career meant but I think it must be because I looked around as a tiny tot and thought, wow! Everything God has made is simply amazing. The trees, the animals, the sky, the insects…I will attempt to give you an insight about the little things (or not so little depending on your perspective) that make me so awe-inspired.

First, the atoms making all matter up. When I look at the structure of an atom and how it greatly resembles a planet, I am immediately amazed. How can something so simple and so tiny be so organised? The bit I love best are the electrons whizzing around like little moons outside of the nucleus of an atom. The fact that there is a space (albeit miniscule in human terms) between nucleus and electrons yet there is an almost unbreakably strong force holding those structures together. And the fact that when you think every small particle has millions of atoms all linked together but all quite independently holding their ground with their electrons orbiting and repelling each other, creating a little force field of protection for their little territory. Then multiply that by millions and you make a little baby whose atoms are organised in equally amazing cells.

Cells are just a feat of engineering. Google the structure of a cell and maybe look at an animation of what a cell is doing all the time. As you sit here reading this, your cells are busily functioning. Making energy from glucose, enzymes and oxygen in the mitochondria and funnelling that energy in the form of molecules called ATP where they are needed for your cell to do more stuff. As the cells work, they are making waste products and heat that they are getting rid of either into fluid around them to go ultimately into blood to be excreted mainly via the skin, lungs or kidneys. The nucleus in each tiny cell is using up some of that energy to copy your DNA either to make little proteins out in the cell fluid (cytoplasm) or copy the cell’s DNA depending on what type of cell it is.

These proteins are what run your body. Your enzymes and hormones. The building blocks to build more cells to replace those that are dying (happening all the time) or  to repair damaged worn out cells (like nerve cells you can’t make more off). The enzymes help you break down your food, absorb it into cells and then process it, making ATP for more energy. They also help you to convert hormones and other chemicals from one form or another to be used in other intricate processes. Some very important security proteins are those that control how your cells are copying their DNA and therefore multiplying – they often have names like p53. In simple terms, they spot if your cells have copied DNA wrong and the new cells are abnormal (those are the cells that either die or could potentially become uncontrollable and may become a cancer). They then stop that cell being made and destroy it. It is only when something goes wrong with these proteins that you fall victim of cancer or more accurately a tumour with the potential to become cancerous. The hormones tell your organs and glands how to function, whether to make more proteins, work harder or relax a little. Other bits like your white cells also help you fight infections by either producing poisons that kill harmful organisms or simply by wrapping themselves around the bugs and effectively imprisoning them.

I will mention cancer briefly because I find it fascinating and scary and impertinent in equal portions. Like I said, cancer is basically a mistake made at some point when making cells. Some of these defective cells will just die because they do not work well enough to process energy needed for them to survive. Some though become super-cells and not only can they make energy, they evade your bodies normal security proteins and start to multiply at a crazy high pace (fascinating!). These cells then take up space they should not normally take up and even more impressively, they somehow hijack your blood vessels by producing proteins that encourage growth of blood vessels around them so they make themselves a nice super-supply of blood, getting extra blood with all that extra glucose and oxygen to fuel their drive to multiply further (making you anaemic and breathless because you are short of oxygen). The ball of supercells (tumour) then grows and grows, taking up space and pushing your organs out of the way, making them function not as well (giving you some of the symptoms of cancer like constipation when they press on something like bowel) or blocking tubes (like the trachea in the lungs so you become breathless eventually or your bile ducts so you become jaundiced and cannot get your digestive enzymes to your tummy to allow you to digest and absorb food so you lose weight). This is the impertinence of cancer. Eventually, it replaces your normal organs and that’s when the real big problems present. That scares me because you have millions of cells all multiplying constantly and mistakes are bound to happen. It takes just one mistake that goes uncorrected and you potentially have a cancer in the making. Goodness gracious me!

Back to awesomeness though. The next thing that never fails to impress me is reproduction. You can’t escape it. People say love makes the world go round. Some say it is sex. Really, it is reproduction. From simple cell reproduction as above allowing a little baby to grow and for a body to keep functioning to actual mating and reproduction. It really is not all about sex. Even ‘simple’ beings like bacteria reproduce by exchanging DNA in a very unsexy way. Have you ever seen snails/molluscs ‘mate’ for example on nature programmes? It is so weird and amazing all at the same time. That is what binds us all living beings together. We are all programmed to reproduce to ensure our all-important DNA is preserved. So sex my friends is beyond physical lust. You are pre-programmed to want to procreate.

Babies in general are simply fabulous (take it from this paediatrician who is daily seduced by their endless charms at work). However, baby girls are a cut above the non-girls (sorry boys). When a little girl is being made, by 20 weeks of pregnancy, she already has ovaries which have made all the eggs they are ever going to make. In fact, she normally has more than she needs in her lifetime (more than one a month for all of her fertile years) and about 80% will degenerate leaving 20% of her (best) eggs ready for when she one day is ready to become a mother. A baby boy in comparison does not produce any sperm so has no capacity to reproduce. At the earliest in a healthy normal boy, sperm do not come into being until the boy is at least 9 years old. So yes, I know I am probably coming across as very feminist but hot diggity! Girls are awesome!!!

I will stop at that incredible piece of biology because I will get too excited if I carry on. When I stop and think about biology, I have all the evidence I need for God’s existence (or whatever you like to refer to that life force that controls us all whether we are willing or not). There is clearly intelligent design at play. Biology did not just happen and continue to happen. It is a true miracle and I thank God that I am human so that I can appreciate all of nature’s amazing-ness.

Tell Your Truth  

I quoted Clint Smith’s comment about fear in an earlier blog and this one here is inspired by the something else he said on the same YouTube video. He is an American who lectures in the States and he says in the video that the only thing he asks of his students when they are in his class is to tell their truth and that nothing leaves the room without their permission. This got me thinking about truth and its importance. I know everybody lies sometimes and actually sometimes a lie is the kinder thing to say. However, I do think these days too many people lie willy-nilly for no good reason and it baffles me why.

My mama and I (in case you haven’t realised it yet from the number of times I mention her in every blog) are very close and I think one of the biggest reasons why that is with each other, we tell our truths. My sister and I never went through ‘teenage rebellion’. We didn’t have anything to rebel about because everything in my home was out in the open. My mama has always been truthful when asked anything directly. Of course, there are things she held back from us when we were too young to understand but as long as she thought we would understand the answers and that it would teach us something, we were told. I knew about the birds and the bees from very early on and so it was never a big deal talking about sex in our home. Because my mama is a feminist and part of her NGO work is empowering women and girls, I attended a workshop she organised in the early 90s back when HIV and AIDS were in the headlines. So before I was 10 years old, I knew about safe sex, condoms, how to put them on and dispose of them safely. Even before that, I knew all about periods and puberty and everything else that was necessary to face growing up.

In the same vein, whenever I made friends with anybody, I would invite them to our home at the earliest opportunity so that my mama could meet them. I knew that if my mama was okay with such a friend, then they were good enough to keep as friends. I could rely on my mama to be truthful. So over the years, we have talked about friends, boys, men, sex, drugs, alcohol, travel, homosexuality, religion, war, the potential for an apocalypse, death and anything else I was ever curious about. We are so comfortable and open that people often get surprised by how much my mama knows about the exact things people would try to hide from their parents. It is only as I have got older that I have started to edit what I tell my mama. This is mainly to do with my significant other relationship and I keep things from her not to withhold my truth but so as not to sour the relationship between my husband and his mother-in-law. After all, ‘they’ say that if you tell your parents about the ‘bad things’ that your spouse does to you, they will harbour it for aeons whereas you might forget it the very next day or week. I am a very lucky girl because in my home telling my truth was not only actively encouraged, it was expected. I am now trying to teach my husband the same and I hope to emulate the same culture with my future children.

In my profession, telling your truth is a GMC requirement and it is set out as part of the duties of doctors which we are sent in paper copy periodically to remind us of our oath. I am a paediatrician and definitely not a surgeon. However as the cookie crumbles, I happen to be doing a surgical rotation (which is ending today. Hoorah!) currently and I have had major issues because of a lack of truth and the surgical culture of aggressive competitiveness and subtle bullying. I particularly had a problem when my father-in-law was taken ill and I was delayed going in for a shift. Long story short, I couldn’t leave him until he was safe and so I was going to be late for handover. The doctor that was meant to handover offered to swap shifts. I thought how lovely, swapped shifts and thought nothing more of it. Then rumours started to fly after I was late for another shift about how I was so late I didn’t turn up for my shift. After a couple of weeks of ignoring the immaturity of it all, I found the senior doctors involved and asked if they had a problem with me particularly if swapping that shift was a problem. They all denied having any issues but I had heard enough to take it to the top consultant and my supervising consultant. They were both lovely and reassured me. I thought ‘Great. All sorted and I’ll put it all behind me’. The rumours continued and I eventually found the source of it all. Disappointingly, it was a registrar senior to me who always made out we were cool. So I had it out with him and asked him to be professional. I am pleased to say once I confronted him, he has behaved in a more professional manner but I must say I will be glad not to have to work so closely with him anymore. I just think that there is no place in a professional setting for lies – everyone is there to do a job and if you are not interested and focussed in the job, maybe you should quit and go do something else.

I have a confession to make. I am rather feisty and not afraid to speak out in most situations. Even as a child, the worst thing you could do to me was lie about me. I remember way back in primary school, someone jealous of me for something or the other said to one of my friends that I had said something about her behind her back. My friend promptly told me because she didn’t believe I would do such a thing but I was so mad that the girl had accused me wrongly that I cried. Unfortunately, in these situations, I still get so angry that I often end up crying because I feel helpless to do anything else. I am getting better at dealing with the anger though so hopefully by the time the kids come along, their mummy won’t go round embarrassing them with her tears. As far back as I remember, I made a vow to myself. Unless there is an absolute need to hide the truth, I shall always tell my truth. And honestly, it feels great!
