My 2nd rule of diving: You can call a dive at any time, and for any reason: no questions asked.If someone doesn’t want to dive with me because I have an implant and wouldn’t be able to save them I would totally respect that.
You just can't force me to dive with you. It has nothing to do with being politically correct, but with my comfort. After all, diving is all about ameliorating risks with a methodology that suits us individually. I might think you're not safe for whatever reason, but I also don't want to get into that with you, either. I've got an issue with my eye and can't see me diving today, might be the only explanation I'll provide. Or it could be that bone in my leg that just won't go away.
