Lust Academy Pt. 23: She's Still Got It!

Seems like it's more than that. Yes, the neurons stay with us forever, but everything else definitely seems to replace itself.Skin: The epidermis sees a fair amount of wear and tear, thanks to its role as the body's outermost layer of protection. These skin cells rejuvenate every two to four weeks. Hair: The body's natural fuzz has a life span of about six years for women and three years for men. Liver: The liver is the human body's detoxifier, purifying a wide variety of contaminants from our systems. It's aided in the process by a constant blood supply and remains largely immune to damage from these toxins by renewing itself with new cells every 150 to 500 days. Stomach and intestines: Cells that line the surface of the stomach and intestines have a difficult, short life. Constantly battered by corrosives like stomach acids, they typically last only up to five days. Bones: Cells in the skeletal system regenerate almost constantly, but the complete process takes a full 10 years. The renewal process slows down as we age, so our bones get thinner.

@Grims Dungeon Of Degeneracy: so, 7 is not "about 10 years?" You said whole body not one particular tissue-- I had cell biology, human anatamony, human physiology, biochemistry-- we talked alot about immune cells, liver cells, blood cells, and pancreatic cells-- you know enzymes and secretions type of things and antibiotics and immoglobulins alot. We used antibiotic to screen cells we grow...

And I used to be a Flight Medic... I was trying at one time to be a nurse, but women lie randomly for no reason!?! Many try to dominate over men, which is why in the military, sorry US military they are officers. Men used to ignore them in WW1...
