Well, think about it. When you were ten years old your brain didn't have so much to remember. As you got older SO many things happen that you HAVE to forget SOMEthings or your brain would burst.
Now, at your ripe old age of 40, it's okay to forget.
I'm 40 as well.

Quick, is my nose growing?
LOL...well, that makes sense! Actually, I'm 30 years "riper" than 40, you young whipper snapper!
Wait... what were we talking about?
