Scuba diving for older people.

Even if there's no age restrictions for practicing scuba diving, some research reveals that at older age scuba diving does become more risky recreational activity for people, and many things that normally are not, should be taken into account when choosing appropriate scuba diving destination. Monterey Bay kelp forest, one of the world's cold-water most famous scuba diving destinations, continuously reports accidents with older scuba divers. Surprisingly enough, those are not novices, but veterans of the generation of divers who joined the sport in the 1980s. Apparently, with age scuba diving skills of some of them got somewhat outdated. Probably, part of the problem is due to the fact that after passing one's certification test, scuba divers are not required any form of subsequent training or follow-up courses. Outdated skills coupled with inevitably poorer physical form, changed body chemistry etc., all that make older scuba divers feel less comfortable in cold water, as well as more likely to develop, say, a sudden muscular spasm that might lead to drowning. Probably, older age should be regaded as contraindication for cold water dives?
