I hope I dont gross anyone out here but I just want to highlight a funny analogy. I have a hard lump of dome shaped skin on one of my toe knuckles, its most likely a callus. Anyway, its been there for many years and apart from it being ugly to look at, its not a problem and doesnt hurt.
The interesting thing is that many times in the past I have attempted to cut it off, often enduring extreme pain and lots of gushing blood in the process. But guess what? No matter how perfect I make the cut, or how much skin I cut away, it ALWAYS grows back to the exact same size and shape.
I dont know, maybe im eating too much protein?!
Kinda makes you think about adipose tissue mass and weight gain / re-gain after dieting doesnt it?
