Ever heard the age-old argument about "If you replace the head of a hammer, and later replace the wooden handle, is it still the same hammer"? A hammer is just an example, though. It can be any object. But what about a human?
It is no secret (hopefully) that your body is constantly replacing old cells with new ones at the rate of millions per second. In fact, by the time you finish reading this sentence, 50 million of your cells will have died and been replaced by others. But don't worry, the life cycle of every cell is carefully controlled, so you should always have just the right number of each type of cell.[1]Only a few cells don't get replaced: Those in the lenses of our eyes, and most neurons of our central nervous system.[2] So, physically, are you the same person as you were 7-10 years ago ( the average time it takes for all replaceable cells to be replaced)?
Thankfully no, you are not the same person...physically or mentally. Your body will of changed (internally, of course) with new wrinkles, more muscles (or less), hair color (mine's going gray), fat content, skin pigmentation, etc. However, your mind will of also changed with new things learned, new memories made, emotions. However, all that meaning said, I believe that a person heart (spiritually) can have the biggest change. The heart to forgive, love, and accept people for their faults and beliefs. A willingness to compromise or agree to disagree with each other, and to know we are on this Earth to make it better place with us in it. If LOVE was everyone's goal, then a lot of problems would be solved.
