when food in stomach, blood flow to stomach and not as much blood for
rest of body. so if you exercise hard after big meal, not get enough
oxygen for rest of body as blood flow more to stomachy.

it's like no good study after eat. blood go to stomach and less for
head. that make for more drowsy and it harder to study.
