Yeah, I reckon that was a myth......I think they just didnt want to feed us.....
I remember that one too. I always hated to eat lunch because mom would make me wait an hour before I could go back into the pool. She said if I didn't I'd get cramps and drown.
They used to make us eat a box of Jell-o before a swim meet too. Not regular Jell-o. We had to eat the mix, the powder straight out of the box. I never could understand why it was okay to eat a box of Jell-o mix and jump straight into a pool for a swim meet, but yet wait an hour after lunch when I was having fun. It never made any sense to me.
