Well it's happened, I think I'm old. I have been told that I could benefit from "geezer gas" on our long dive trips. I am a 43 year old former PADI MSDT who is now interested in continuing education. My question is this, do I need to take one of the silly padi nitrox courses where you have to dive? Can I take a crossover course from another agency and just learn the technical stuff without paying good money to prove that I can inhale off a scube tank? I am sure this has been covered before so forgive me for beating the same drum. Thanks for your help
