Does your skin change every 7 years?

Answer 1

If you average all the cells as they live, multiply, and die, many sources say that it takes seven years for all of them to change in your body. This is somewhat true, but also somewhat misleading. The truth is that different cells have different lifespans. For example, the nerve cells in your brain do not multiply and they last for your entire life. If any of them die, they do not get replaced. At the other end of the spectrum are the white blood cells in your body. They have the shortest lifespan and some of them live only a few days.

So, in actuality, the concept that your body changes every seven years is not exactly true, because even though most of your body cells will have reproduced and replaced themselves, not all of them have, and some have replaced themselves many times over during those seven years.

Answer 2

We regenerate constantly in a way, in terms of cells. I'm going to give an answer that strays this topic a bit, but it should help you all understand . We don't regenerate in that sort of aspect. Our cells multiply (which is a form of regeneration because mostly when our cells multiply most of the old ones die after a while, and there are small string like things attached to each cell that over time (in terms of ageing and multiplying) get shorter and shorter untill it runs out and leaves the cell open causing them all to burst or defect) (death by old age) this can even kill you if your medically healthy and is just the way of life. Unless we can preserve these cells or live without them, living over 120-30 is pretty much impossible. Oh and may I add that the multiple rapid cell regen (some forms of cancer) is so hard to survive for a long time is because if its left for too long our cells will multiply so much either causing burst or defect, or overloads. I hope I explained this okay - basically we don't regenerate in the form you are talking about, but we are constantly regenerating/forming new cells which is somewhat a form of regeneration

Doctors have told me this for years, but the one who prescribed my barbiturate yesterday said it wasn't true. He's a great doctor and been around for years, so I'll take his word over the others.
