Playing in the pool with children is one of the simple joys in life. I’ve been doing it for the past 20 years or so, and have always loved it. Kids have fun naturally and find such joy in being in the water. A special bond develops when a child puts their faith in you while they learn to swim. It’s very intrinsically rewarding as the adult, and dry-land observers can see the serotonin bursting out from the pool. We are social creatures, and children are the future. Simply swimming in a pool together can show you that.
