58. Certified OW in 2021. Self-certified as a Warm Water Pretty Fish snorkeler in 1995. Spent the next 25 years limiting myself to the surface because I was convinced (without medical consultation or empirical evidence) that I would not be able to dive due to the atmospheric pressures involved. When a relative by marriage wanted to get an OW certification I agreed to do a PADI Discover Scuba dive. 15 minutes into that dive I discovered that (1) the atmospheric pressures underwater don't affect me the way that I thought they would and (2) that I was officially addicted to scuba diving. Still limiting myself (for now) to Warm Water Pretty Fish diving because I am a wuss who truly detests being cold, although reading several threads here I can see the attraction to cold water diving for braver souls than I...
