RB -“Health – Part of lifeguarding skills is “common sense”. If someone doesn’t have it (by loosing their chezkas kashrus), then they are not qualified to be a lifeguard.”
1. A lot of people don’t have common sense, but most of them are still employed, married, etc.
2. Who are you to determine who is qualified to be a lifeguard?
How many years lifeguarding experience do you have?
