Your body is a rebuilding machine

There is often a large misconception around "change". How to make it happen, and if it can in the first place. 

What am I getting at? If it's one thing that we should learn from science it is that we don't know everything and keeping an open mind is of paramount importance.

Let's take body cell generation & regeneration for example. It was once thought that your heart does not have the ability to reproduce cells. Well, that's not the case. Although it does this slowly, it was recently discovered that our heart does have the ability to do replace cells, and does so on a regular basis. It does however take much longer for the heart to totally renew all cells (on the order of 20 years) verses say your bones (about 10 years), your skin (2 to 4 weeks), your lungs (2 to 3 weeks) or your intestines (2 to 3 days!).

The good news is that you can take advantage of all this and use it to your benefit!
