Scuba Pro

I was talking to a friend about scuba diving last week and mentioned offhand that I have my open water certification. He suggested we dive sometime. I mentioned it'd been a while since my last trip. "Let's see, I got certified when I was 12 years old...so it's been 22 years." Though my safety record is impeccable, there are some gaps in my expertise. Also, I think all of the plastic in my mask and fins has dried up and rotted, so I won't be able to see or swim when we go diving.
