The skin of a Panamanian golden frog contains enough toxin to kill 1,200 mice.
Depending on your size, your skin weighs 10-15lb.
The skin of a hippopotamus weighs a ton.
Each square inch of human skin has 65 hairs, 650 sweat glands, 1,300 nerve endings, 9,500,000 cells, 19 yards of blood vessels and 78 yards of nerves.
Nobody knows exactly how many holes there are in human skin. There are an estimated 2-5 million hair follicles and perhaps twice that number of sweat glands.
An average 10 millionbacteria live on each sq cmof your skin. Around thenose and in the armpit,the figure rises to 100 million. On the teeth and in the throat there can be 10,000 million bacteria per sq cm.
The outermost layer of your skin is made entirely of dead cells, which are replaced every month. We shed skin at the rate of 25,000 flakes a minute – over a million pieces an hour.
People get through about 900 complete skins in a lifetime.
Unlike a human heart or a kidney, our skin never fails.
It is true, I have had a heart attack, but I’ve never had a skin attack.
Indeed, I have been running a dust experiment for the last couple of years.
The famous and utterly outrageous homosexual, the late Quentin Crisp, lived all his life according to him, with his theory of dust.
He said that dust only builds up to a certain level and then stops, and builds up no more.
I can confirm that the cabinet on which my tv rests has not been dusted during that time. It is not overloaded with dust and appears to have the same amount as a couple of months after the experiment started.
Of course, I could have been breathing it into my lungs, but if that was the case, you would expect my asthma to get worse, but it remains as it always has.
I seem to have been running an asthma experiment too, with the same result.
