Actually plenty of excuses. I once had a job waiting tables in Gibbs Hall, 1977-1979. I got to eat there. Food is everywhere and good! Sunday night, after a game, steak and lobster if they won, beanie weenies if they lost.
Also, think of all the catered meals these guys have to eat.. SEC media days, Big orange caravan, entertaining recruits. UT has a pretty nice "restaurant" for all kinds of occasions just behind the "Tennessee Terrace" (see pic).
Also, don't know if you've ever had a job where you put in 10-12 hour days, but it's hard to get an exercise routine in there. Just ask Jim Chaney.
Not many, I used to use a homemade cool can with dry ice on a 1968 Plymouth GTX when drag racing (which was often)
Later learned to block off the heat risers under the intake with stainless steel thin plate to prevent Vapor lock and keep under the Carter AFB cool
Those were the days I most enjoyed while growing up
