Thinking about joint mobility I noticed a woman walk past my desk at work the other day with a great gait and a real "wiggle" in her walk. What really struck me was the evident healthy mobility in her pelvis and lower back.
I've been thinking about mobility quite a bit recently and what this walk made me think about was that such mobility is a sign of youth and fitness.....and therefore sexual attractiveness. Older people are not mobile - they do not move the same but they are "solid" and their movements look less fluid.
Keeping mobility keeps you looking young.....and attractive.
