Living in the desert I will not go in our pool unless the water temp. is at least 88 because of the low humidity. When we lived back east water temp. of 72 felt refreshing because of the higher humidity. Hawaii is pretty humid so water temp. of high 70's should feel pretty good. JMHO, for what it's worth.
I would like to see the 71 year old’s story just to compare. It may have been a rough swim for him, but he may just be in great shape.
When did Ferdinand first release this video?
