Pah, your son's a wimp, tell him if there's not ice in it it's good to go in. If there is ice in it, it's even more rejuvenating! After all, polar bears have fabulous skin!!

Anyway, we're the same, gas heater turned on in time to be up to temperature for the guest arriving. (Oh, and when we go, we even have pool heating in the summer as we're even bigger wimps!!!).
