    Is the skin the most boring organ in the human body?

    Yes, yes it is :sadnod:
    Why do your fingers go all wrinkly after going in the water :beard: I've always thought that because there's more water, surely it shouldn't wrinkle - and I can't see there being less water when you're submerged in a pool of the stuff :p:

    Must be relaxing to be a dermatologist though - no on-calls, not really long hours, no real skin emergencies to deal with...

    Oh, we were thinking about it in the wrong way. The wrinkles are caused by water entering rather than leaving because of there being a lower water potential IN the skin, well it seems so according to yahoo:

    Your skin is comprised of two layers -- the epidermis and the dermis. The epidermis produces an oily protein called sebum, which is effective in repelling water. It's also the material that causes fingerprints.

    Inevitably, a nice long soak in a bathtub sloughs off the excess sebum from your epidermis. As a result, your skin starts to take on water. The top layer of the epidermis is known as the stratum corneum, which is Latin for "horny layer." These are the tough, dead skin cells that are constantly being sloughed off your body in your clothes, your bed, and in the form of dandruff. Disturbing, but true.

    Your fingers and toes have especially thick layers of stratum corneum. Once deprived of sebum, they swell up with water, causing wrinkles. This osmosis effect is harmless and temporary. One you get out of the tub, the extra water evaporates, leaving your skin even drier than before because there is no sebum to help retain moisture. This is a good time to apply lotion or oil to help your skin retain some of the water.

    Mmm, but I've always thought that as there's more water in the skin, your skin should swell up or something instead of wrinkling up - just how "fluid" is skin :p: Interesting anyway, thanks. I might wiki it later as well.

    Well I'd have thought that too, but I don't suppose that all of it could swell because I doubt that much water can enter, because not all the sebum comes off and there must be some sort of barrier against you becoming a swollen mess :p: so it might just be a little water entering some of the layers that causes it to wrinkle by changing shape a little by becoming more tense in some parts.

    Oooh, more answers:

    There are various theories of why fingers and toes wrinkle in water. Most biologists suggest that the tough outer layer of skin made up of dead keratin cells is responsible. Keratin is a protein found in hair, nails, and the outermost layer of our skin.

    While a person is in the pool or a bathtub for a long time, an oily protein called sebum starts to slough off our hands. This then lets the liquid to come in contact with the dead keratin cells that absorb water. This absorption causes the surface area of the skin to swell, but the outer layer is tightly attached to the living tissue. To compensate for the increased surface area, our skin wrinkles.

    Why does this happen to hands and feet and not to other parts of the body? Because the hands and feet have the thickest layer of dead keratin cells. Our hands and feet are subjected to a lot of wear and tear.
    That one explains it better I suppose.

    I had the third hep B jab last week, and apparently they cant take blood within 7 days of that.

    Funny how when they said no, they all went "But you'll come back next time yes? YES?" :laugh:

    Anyone know a reason for this?
