We are all going to need help at some point in our diving history. It is up to each of us to decide whether we are going to let a disability or inability to do things as well as we did in the past get in the way of a wonderful opportunity to dive. Because of multiple joint replacements, some of which act up on occasion, I sometimes need a crew member to haul my tank/bpw out of the water. I always ask ahead of time whether or not that will be a problem, and always tip well. No one has ever declined to help, not knowing whether I was a generous tipper or not. When paired with a buddy, I always let the buddy know of any potential issues, and the buddy can decide if the pairing is OK. In reality, I have found that when in the water, my buddy is far more likely to need my assistance than me needing help. I take pride in knowing I am a buddy you can count on in times of trouble.
