27 years. There was a big family break in the middle, then back to it...what's up with these certifications anyway?
And the internet came after the 60/70/80's...so maybe the REAL old timers (except of course Forrest) never got wind of it and are too senile to figure it out now (Forrest - I know...or at least I think I do, that you aren't senile)? So the >10 number is likely much larger...Hell, I'm 51 and finally managed to turn on one of these darn electronic, two finger, Jeano Beano talky thingies...even with post-senile syndrome at play!


and I have been cave diving on a continuous basis since 1998 when we first earned our full cave certification (it would be 1997 except we were only Apprentice Cave Divers for a year....)
I started cave diving in 1973, just after finishing high school.
