YOGA KEEPS YOU YOUNG, at least from a physiological perspective. Regular yoga practice can counter the effects of aging by regularly moving joints through a full range of motion, improving strength and balance, and reducing stress.
UPON SURFACING, I heard a fellow diver ask, “How cute are those brooding anemones?” This observation piqued my interest because I’d never heard of this behavior despite a lifetime of watching nature documentaries and reading dive magazines.
