The individual hairs on my head are fewer and thicker and coarser, and have far stronger chemical bonds than yours – unless, of course, you recognise yourself as having the same genetic quirk as mine. My immune system is slightly stronger, but on the downside, I am much more likely to suffer from Tourette’s, Parkinson’s and, as a woman, endometriosis. The pH of my skin is more acidic than it would be otherwise. I can manufacture adrenalin much more quickly as a result of it, and my cells can take up that adrenalin much more speedily too. For example, if I have surgery, my genetic quirk means I need 20 per cent more anaesthetic. They mean that not only do I look slightly different from other members of my family, but, physiologically, I differ from them, too. The most obvious result of this particular quirk is that my melanocytes operate differently from most people’s but there are other differences that run much more than skin-deep. Neither of my parents had any idea they were carriers until I was born indeed I’m the only example of this particular genetic oddity in my family within living memory. You may carry this same quirk somewhere in your DNA, but only two per cent of people will have it in the same double recessive form, making it visible, like me. I have this genetic quirk, one that is unknown to 98 per cent of the population of this planet. I have to start this with a confession – I’m probably not the same as you.
