I know that human skin is self-cleaning (almost certainly courtesy of The Ladybird Book of the Human Body, Look & Learn or similar) but I also know that it is not very good at it. In fact, I do know people for whom the whole arrangement has irretrievably broken down. Dirt, like energy, cannot be destroyed. It merely moves from your body to your sheets. Besides, if I understand it correctly, skin does not actually clean itself, it merely dies and drops off, taking the muck with it – although in my experience, seldom quickly enough.
Fifty percent of household dust is dead skin (I hesitate to think too deeply about what constitutes the other half) and it is estimated that the average adult could fill an average-sized bungalow with sloughed dermis during a lifetime. If you don’t believe me, look inside your sock after a long walk.
The human body is an amazing thing – I certainly wouldn’t be without mine – and I thought that it was about time that I took a look at exactly how remarkable it actually is. (Not by using a mirror you understand. That is not an amazing thing. That would be of interest only to an Eskimo who wanted to estimate how many candles he would be able to make from it.) I undertook extensive research (five minutes on Google) and this is what I found:
- If laid out end to end the blood vessels in your body would stretch out to 100,000 miles and you would be dead. About two thousand gallons of blood are pumped around the body every day, enough to fill around eight average baths – although I wouldn’t necessarily recommend it.
- The brain, like the North Sea, is eighty percent water – although the other twenty percent is not the same. It – like a geriatric’s love life – is more active during sleep.
- The strongest muscle in the body by weight is the tongue. I can think of nothing to say about that which would not result in my arrest if ever I set foot Alabama.
- The nose can distinguish over a trillion different scents, at least a million of them associated with feet. Noses can be educated to detect hundreds of different aromas in a single glass of wine – although not, unfortunately, pretentious bullshit.
- The small intestine is approximately twenty feet long – although it can feel like inches after a Mexican meal.
- A sneeze can travel at up to one hundred miles per hour: ten miles per hour quicker than the hand bearing the tissue.
- The average human body contains enough carbon to make nine hundred pencils and enough fat for seven bars of soap, which explains why most men think about sex far more often than they think about washing their hands.
- Humans are the only animal to blush – and almost certainly the only one with reason to.
- The fastest growing hair is in the beard – which is why your granny has to shave so often. Irrespective of speed of growth, beard hair is left standing by nasal hair which, in my own experience, can attain the girth of a tree-trunk overnight.
- In thirty minutes your body produces enough heat to boil half a gallon of water. Presumably, if you were to lay in a cold bath for long enough you would eventually be able to have a long, hot soak without troubling the boiler. Stay there a little longer and you could probably cook a lobster.
- The average person has 67 different species of bacteria in their belly button. The average five-year old has 67 different species of bacteria on everything they hand you.
- Babies cannot shed tears until they are about one month old – but boy do they make up for it afterwards.
- Humans have fewer genes than a tomato. Donald Trump has fewer brain cells.
