Why do we die? I know this sounds like a silly Craig question…but think for a moment…. As far as I can tell with my stunning history of biology lessons you die because your body gives up, your organs can’t last forever right? Parts become worn out and can no longer perform their tasks very well and so eventually they all add up.

Did you know that the last person in the US to die of natural causes was in the 50’s… Now my first (rather stupid) thought was how bad the general populous’ health has got in the states as they all must be fat etc. The actual reason is because they started to record more information. So for example a heart attack is natural, as are some cancers (depending on their cause)… You get the idea.

What I don’t understand is why a heart attack can happen say after you are 50, yet before that you almost never have them. Now if I’m being wrong here do tell me, but as far as I remember a heart attack is caused by the clogging of a couple of arteries around the heart. So why isn’t our blood filtered to stop this…. It seems pretty sensible to me. Or how about our skin. Now we have 7 layers (give or take) and we loose on average one a month to be replaced with a nice new one. So why the hell does it wrinkle?

Actually, I’m going to stop typing this, I think all I’m actually showing is how little I know about how the body functions. The point I was trying to make was why do we die when all our cells seem perfectly capable or regenerating.
