20 page report on aging curves, very interesting, especially the graphs.
Some interesting things I learned:
* In more recent times (1980 on), the peak age is more like 28, not 27, and players are aging slower. This shows the effectiveness of modern medicine and training programs! Also, players arent experiencing nearly as great a total decline from their peak now, as they did in the past.
* The area around the peak is more of a plateau, everything from 27-30 or so if very close together.
* In the early 30s, players dont decline as much as I would have expected. Subtracting .5 win per year for a player as they age is probably too much, until the late 30s.
