Yes -- you've pointed out two truths. The first is that all people have reduced joint motion as we age, including motion in the spine. With each passing decade we seem to lose a little more. Secondly, men seem to be affected by this more than women.

This change is accompanied by reduced peripheral vision (seeing out the side or corner of the eye). Scientists aren't sure all the reasons why this happens yet. Vision, hearing, balance, and neck motion all seem to be connected. Change in any one of these can affect the others.
