Sharkey, Unless there has been a ton of pygmies out there statistically decreasing the average size of the population, I can't see how you havn't noticed how much bigger (including height) the athletes are (and the population as well) When Wilt chamberlin played in the NBA in the early 60's there were maybe 3 7 footers. Now there is probably close to 100. And a lot of them have the athleticism to handle the ball (Dirk Nowetski). It sure as hell seems like we are bigger stronger and faster than 40 years ago. There are quarterbacks who weigh 260, with no fat. They just don't look it because you are watching them play surrounded by 6-7, 350 beasts. Now there arn't any 7 footers in the NFL, but wait about 20 years and there will be. I don't know where you got your stats, but if they are accurate in regards to people being the same on average as they were 40 years ago, then damn, I must be missing something. It sure as hell looks like it. However, you can't dispute that the difference in size from the early part of the 20th century. Like i said the average height was 5-6, the average shoe size was a size 6. I think improved neutrition during the baby boom era may be a factor- but I don't have any evidence to back that up.
