Scuba diving is a great sport to take up at any age, since it offers a thrilling, full-body workout that’s easy on joints and requires little stamina. If your overall health is good and you have access to the right training and equipment, go for it! Take a certification course near home, or join an introductory resort course to learn safety basics. Certification begins gently in a pool, and ends in open water. Once you’re certified, you can go on dives wherever they are offered.
As for risk, recent statistics show that one out of every 211,864 dives ends in a fatality (that makes scuba diving less likely to kill you than driving; one in 5,555 drivers die each year). But if that’s too much risk for you, there’s always snorkeling, which is a less dangerous way to explore under the sea.
Scuba–short for “Self-Contained Underwater Breathing Apparatus”–is defined as pleasure diving to a depth of 130 feet. Certification courses are available from the Professional Association of Diving Instructors and the National Association of Underwater Instructors.
