I'm no spring chicken, but believe it or not, it was my parents who, only a few years ago, inspired me to dive. That, and a family reunion trip to the Great Barrier Reef.
I snorkeled for a great many years, and had lots of fun doing it, but never ever considered scuba. Then my parents, who were in their mid 60s, decided to get certified in preparation for the trip to the GBR. My father got his C-card. My mother's open water dives were in not so great conditions, choppy water, wind, current, and got she tired out on the surface swim, so didn't get her C-card, but the thought occured to me: if they can do it, why can't I? And so I did.
