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.

It is Not a Popularity Contest

Some people have thousands of friends (and followers) on Facebook (FB) and it makes them happy because it makes them feel popular. Or maybe they truly are friends with that many people. Lord only knows how they would have the time to have so many friends. What with so few hours in the day and probably needing to do something to earn a living (work anyone?).  But anyway, if you have that many friends, good on you, you social butterfly you.

At one point, I had more than 500 FB friends. I cannot remember what inspired me to look through my list of friends about a year after joining FB and I realised how many ‘friends’ I had not spoken to, called, text or even heard any news about in over a year. And how that lack of contact did not affect me in any way. Which led me to the conclusion that a fair few were not really friends. Hardly even acquaintances. So what did I do? A deletion binge. I looked through the list of friends and if I was struggling to remember how we met, they were deleted. I also deleted everyone I had not had any interaction with in over a year and those who were friends of friends who had added me and I felt obliged to accept but had actually never said a personal word to (virtually or in reality). At the end of my binge, I had less than 200 friends. That was nearly 300 friends who had access to a lot of personal pictures and thoughts and insight into my life that I had got rid of. I also then made my FB settings more secure. People cannot read many of my posts unless we are linked. They cannot see most of my pictures and they cannot send me private messages in many cases (if they do, I have set it up so it goes into a ‘spam’ folder). This experience was so cathartic, I now fondly think of it as my ‘spring clean’.

The spring clean is now an annual event. It is not always in the spring mind. It is whenever I have a quiet moment but usually once a year. Since this ritual started, I have noticed one thing. I don’t get ‘spammy’ messages on my wall anymore. I do not get ‘friends’ judging me because as a Muslim, I choose not to wear a scarf. Or those who judge me for cutting my hair. Or for expressing my candid opinions on politics, religion, gender equality, relationships, sexuality and other controversial issues. I do not have to defend anything I post on FB because what you see is what you get with me. If any of those who have made the cut decide to go all judgemental on me, I am not shy pressing the unfriend button. I mean, there are plenty of strangers out there who could (and do) judge me for all the wrong reasons. My race, my colour, my religion, my accent, my slim build, my honesty, my kindness etc. I think those I choose to label as my friends should be able to take me as I am. Of course, they are unlikely to love every aspect of me (let’s face it, even my dearest mama doesn’t love my stubborn resolve or my willingness to take on fights/arguments). They are entitled to their own opinions and they can debate their point of view but if we end up at an impasse, I expect them to be able to agree to disagree.

Lastly, being human with all of my flaws, sometimes I unfriend people who may have good reason to disappear off FB. God knows that I have done that on occasion so perhaps it is not a lack of friendship between us two. In some cases, I find that out and I add them back on. I will also accept them back on should they request me after I have unfriended them. In a nutshell, what I realised when the spring clean commenced was that if I do not surround myself with too many ‘friends’, I will expose myself to less B.S.

N.B although FB has many drawbacks, it does allow me my spring clean. Much harder to do in real life although in real life, I am not friends with people I do not get on with genuinely. One advantage of being a busy paediatric doctor is that my social life is limited so I have to choose carefully how I spend my precious time. Therefore, only true friends remain naturally. In reality, I would probably say I have less than 50 proper friends and of those, less than 10 that I would not hesitate to call and say I need you or can I come round for a cuppa? Less than 10 who I would call with good news as soon as I get it. Less than 10 who would know about all of my major upcoming life events. Less than 10 that I would not mind seeing whenever they or I needed to spend time together. The few who would always have my shoulder to cry on, my ears to listen and my laughter to share. Those who have an open invite to stay at mine should they need to. Those are my true friends. How lucky I am to have those few special ones in my life.
