Remember when your parents told you that you had to wait a half hour after eating before you could go back in the water?
Why did they say that, anyway?
How many times have you eaten a full meal and went swimming right away, no problem?
And how would only a half hour make any difference?
Your stomach takes longer than that to digest food.
Mystery solved:
They said that because THEY wanted to enjoy THEMSELVES for a half hour after eating INSTEAD of having to watch YOU.
Because if YOU went swimming right away, THEY would have to stop having THEIR fun to resume playing LIFEGUARD.
