Starts at 8 minutes. This man is a Christian which some people might object to. I get lots of info from his website. Liver regenerates every 365 days, skin renews every 28 days, intestinal lining renews every 3 - 5 days, bones repair in 6 - 8 weeks, muscles take 6 - 8 weeks to heal. Stem cells can help. Pancreas (diabetes) can regenerate 6 - 12 weeks but hard to heal it, kidneys and adrenal glands 6-8 months, heart can get scarred and doesn’t regenerate as well as the kidneys, if you have a stroke get oxygen (or a hypobaric chamber-immediately). Brain/nerve tissue takes the longest 1 year - 12 years. Thyroid takes 3 - 6 months. Our body is almost completely new each year
