My answer to How long does it take for your brain to fully replace all its cells?

Answer by Connie b. Dellobuono:

• Your outer layer of skin, the epidermis (apart from the thicker dermis beneath), replaces itself every 35 days.
• You are given a new liver every six weeks (a human liver can regenerate itself completely even if as little as 25% remains of it).
• Your stomach lining replaces itself every 4 days, and the stomach cells that come into contact with digesting food are replaced every 5 minutes.
• Our entire skeletal structures are regenerated every 3 months.
• Your entire brain replaces itself every two months.
• And the entire human body, right down to the last atom, is replaced every 5-7 years.
