for some people it is in the center, and for some people it is on the right side. However, for most people it is on the left. And we only have one heart because we only NEED one heart.
If the true need for humans to have two hearts had at some point in history become evident, then through time and years of evolution, only the strongest of humans (those with 2 hearts) would have survived and reproduced. Thus, future generations of humans would have two hearts. Evolution is amazing. But as it is, we only need one heart.
two hearts would be nice but i rather have a bigger heart and use the other half for something else :)
