"indeed, it has been suggested that there isn't a single bit of us, not so much as a stray molecule- that was part of us nine years ago." "most living cells seldom last more than a month" "brain cells last as long as you do. Toy are issued a hundred billion at birth, and that is all you are ever going to get."..."the good news is that the individual components of your brain cells are constantly renewed so that, as with the liver cells, no part of them is actually likely to be more than a month old." Life, it seems, is insistent on change. For better or worse, nothing will ever be the same as before. Best friends, girlfriends; mothers, fathers, sisters, daughters, all to be different all to be changing. You can never be dependant on anything to stay constant. Ever. I wish that i could control everything. Make it stay the same. In some godly way, life the fantasy of never-changing eternity. I highly doubt that exists.
