Still shy of 50, but I think I have some "prerequisites":
- Last week my son and I set up a 40cuft bottle for use as a pony and eventually a stage bottle. I insisted we go with a full size SPG since there is no way I can read a "button" gauge even with my prescription mask.
- I wear bifocals - hence the problem with #1 - my mask isn't.
- I feel flattered when the young (to me anyway) girl at my LDS calls me "darlin". Of course she calls everyone that, but what the heck.
- I'm the oldest in my DM class - 30 years on the youngest, and I still beat him when we did the snorkel swim.
- I called a dive last month. We had to walk about half a kilometer completely geared up to get to the drop-in point. I got about 100 metres and my back would not take it.
