When I got to a certain age I started having a little bit of trouble with my vision. I am a heavy reader and this was quite a challenge for me. Right around the time my vision started giving me trouble two people I know, who are the same age as me also started having trouble with their vision. We all ended up getting glasses around the same time.
What's my point here?
Well, this little coincidence got me thinking. Is something going on here? Or is it just a coincidence? I did some research and sure enough, if you have had normal vision eyes since birth it is pretty certain that your vision will deteriorate at a very specific and linear rate. An ophthamologist can tell how old you are by examining your eyes or by just looking at your prescription.
This is mind boggling to me. What is the purpose of this? Why all these changes as we age? Skin, organs, eyesight, hearing, teeth. The whole shooting match. Why the decline? What is the purpose that is being served here?
Ok, this is no big revelation. But the thinking here is that nature always finds the optimal solution and it seems to be a pretty optimal solution to insure no individual of a species lives too long. It is necessary, for flexibility in the species, for new individuals to enter the stream.
That's the easy answer. But are there other possible answers?
How about the "Everybody gets a turn answer?"
It sounds silly but it could be true. The plan could be to give everybody a turn at the mystery and the miracle of life. Why not? Kind of like a pass on the roller coaster. Hey, you had your turn now step aside and let somebody else ride!
