I have become more conservative, my risk delta is reduced and this is not just for diving but everything. But I still ride fast motorcycles, just raced a 100 mile Hare Scramble, race my bicycles and do all the things I have always done. My fitness standard, since I took up triathlon decades ago when I was, oh, maybe 28, has been that I should be able to get up from this couch and do a triathlon at any time. That is an International distance, 1.5K swim, 40K bicycle, 10K run, and I can. Of course not as fast as I used to, I was sorta semipro for a short while. I guess I am lucky, I take no medications of any sort and have always been healthy and aside from the bicycle crash (dogs) that shattered my left femur and a mild stroke (is there a such thing) 12 years ago, which was an attitude adjuster for sure, I am pretty much good to go.
The last year+ has been hard for me to dive due to the C-word but a month last fall in the Keys and just came back from another month in SoFla plus some planned trips coming up that were delayed multiple times due to you know what, things are looking up. I have no interest in cave dives, wreck penetration and "Bereavers" but I am pretty much good to go. I do continue to simplify and upgrade my various SCUBA rigs. I invested in a new camera rig and I plan to dive for years to come. I may turn the conservative factor up on my computers.
And just to say, depth is an artificial limitation somewhat, it is the nitrogen loading delta that is the concern, we can achieve similar loadings at 60 feet as we can at 120 feet, just takes longer, getting bent either way might probably hurt just as much. But, yes, 100 feet is a nice round number, but if I have some good reason to go deeper, then I will. I am 67yo.
I will relate this. I was on a three tank dive trip. On the third dive, I rigged up and then tried to stand up so as to reach my camera and get it clipped in. I would not move. Oh, darn, I forgot to remove the tank hold down bungee. So, I slipped out and turned around to find that I had not forgotten to release the bungee. I quietly slipped back into my rig. I thought nobody noticed, of course the mate belts out, "tank heavy huh!" Yeah, guess it is. It was embarrassing because I was the youngest diver on the boat! Dive, Dive, Dive! It is GO time!
