Preventing common ailments is simply a matter of raising our own body awareness. Whether or not we acknowledge it, just about every move we make, every breath we take, is an aspect of yoga; from squats, flexions, and inversions, to stretches, twists, and balance. Yoga simply gives it a Sanskrit name. Just think - raising our hands overhead to yawn is hasta uttana; folding forward to pick up a pin is pada hasta; in half squat trying to button a child's shirt is utkata...the list goes on. So let us be aware of the good it does our body every time we stretch, not to mention how good it feels. Don't just move. S-t-r-e-t-c-h.
