Happens, key is to not panic, overswim. Yes being a beach lifeguard is a whole league different than a pool, lake guard. We averaged about 10 saves a day when the rips were ripping. I had one guy try to drown me as he was in total panic, punched him in the mouth, dove under and grabbed him twisted him around and came up with my arm under his chin to get him in. He was drunk to boot. Quickly escorted out by the staties . 75% of days were lake conditions though. If you are at a beach and its rough stay at knee level and watch them kids like a hawk.
