I wish I could repair the arthrosis in my neck, I'm an otherwise fit man and I get nailed down by bizarre pains that strike me down when I walk. I can't bike anymore either as my neck hurts like crazy. All I need is to regrow the thin layer of biological Teflon between my vertebrae I guess.
I'm baffled as to why my body seems to be able to grow an endless supply of utterly useless hairs and cherry angiomas, but a few microns worth of slippery fat on the end of my bones? Nope. Not happening.
Clearly my cells were able to do it ONCE, can we do it again, please?
This is the future, electronics is mature, computers have become this hermetic playground whose benefits elude me, but biology is really still in its infancy.
