Posture
The other night I was walking through the neighborhood, and I saw a jogger coming up the road. It was getting dark, so I couldn't really make out anything except the outline of the person. I noticed the person's posture was less-than-great, and so I guessed that it was an older runner. As the person got closer, it turns out I was right.
Posture really seems to take a nose-dive during aging. If you compare a college-aged recreational runner to a jogger in their 40s, the difference in posture is dramatic. I don't know if resistance training alone is enough to maintain good posture through the years. Perhaps some other special exercises are necessary.
Does anybody have any good resources on posture? I have a Paul Chek book somewhere in the basement, but that's about all I've got.

Poor posture may signify the end of the neotony stage and the beginning of gene expression that produces a posture closer to that of our ape cousins. This was discussed, in general, in a recent Art de Vany post. He believes that life extension will lead to physical, but not necessarily mental,apelike characteristics.

From Doug McGuff, Ultimate Exercise website, Health-Related Issues article: "What all these women will have is a very significant degree of muscle loss, particularly in the muscles between the shoulder blades and upper spine. With the loss of tension produced by these muscles, the forward pulling forces of the head, shoulder girdle and arms gradually causes collapse of the anterior (front) aspect of the spine."
