I am looking at the poll I started several weeks ago and am finding what most full cave divers have told me in the past.
To be an active full cave diver you must have time and money. By the looks of the poll this is a true statement.
The most common age is the 50 to 59. Not only does this group have more time they have a family that is grown. I know that when you have family responsibilities that the priority of diving becomes secondary. Also this age group generally has more experience and is less likely to change their passionate hobby.

If anyone out there that entered the poll has other reasons why he or she fells that the 50 to 59 age group is the largest I would like to know.
I am also doing a study of physical conditioning in the dive community. This will be interesting to compare the ages with the physical conditions of divers in the different age groups.

Dive safe and stay in shape.
