Just don’t get fat and stay that way.
More than 40 years ago when I went to the University of Washington my weight was spot-on for my height. A couple years later my sister had to gain weight to be accepted to the UW because she was underweight. One of my high school friends who was quite large told me he had to lose 80 pounds to get into the UW. He was pretty much a genius but considered too fat.
Most students were not aware of weight standards since back then hardly anyone was overweight so they never heard about it. When I tell people that now everyone seems to think that policy was racist and discriminatory. The Washington state tax payers did not want to be paying half the fare for fat or almost anemic people because they were not a good investment. That was back when tax payers had a little sense in Washington state.
