Regarding the June 30 Health & Science article “The warning that you should delay swimming after eating holds no water”:

My friends and I figured out the reason behind the myth of having to wait 30 minutes after eating before swimming when we were kids in the 1960s. After feeding us, our parents needed a break to feed themselves and have a smoke before going back on duty watching us. – Brian Peterkin-Vertanesian, Hyattsville
