I guess it's OK that I was turned down by MIT after I applied. I couldn't swim then and I can't swim now.
I don't know how such requirements survive in these days of the Americans with Disabilities Act and Title IX.
As for the argument that such requirements are necessary because "Anything that prevents people from dying needlessly is a valuable skill", I wonder how many institutions would require that one be able to put 10 rounds through a target from say twenty paces? That seems to be a more valuable skill these days than being able to tread water or do a breast stroke (no pun intended).
