You Don't Need to Wait An Hour After Eating to Swim
There has never been a reported case of drowning caused by stomach cramps related to eating. However, cramps do frequently occur while you are swimming. They are usually caused by dehydration and the fact that you are using muscles that you do not regularly use when you are not swimming.
Multivitamins Don't Actually Make You Healthier
There has never been a study that concluded that multivitamins are actually beneficial to one's health. In fact, more studies have concluded that some vitamins lead to an increased risk of cancer. Keep that in mind the next time you go out and spend $200 on supplements.
