Scuba in older-aged divers.

As the population gets older, coupled with increased awareness of good health practices and the recognition that fitness contributes to participation in activities generally appropriate for younger individuals, decisions need to be made about what are appropriate activities for the older-aged scuba (self-contained underwater breathing apparatus) diver. It is essential to appreciate the distinction between chronological and physiological age. Three factors, namely fitness, comorbidities, and mobility and strength are fundamental when making decisions about participation in activities in general as well as in scuba diving for older adults. There is almost always a time to call it quits for everything.
