Actually, recent studies indicate that most of our body is recreated in less than a single year. It’s just that some cellular structures take longer, like our bones and the rods and cones of our eyes.
If this is true, then it stands to reason that anyone who has the time, knowledge and fortitude could make for themselves an entirely new body. Sound exciting? It is! Believe it or not, it can be done! Need a new liver, colon, or heart? How about an entire new lease on life?
