Keep in mind a lot of people are not just coming to med school straight out of undergrad.
Many people are non-traditional students with families, careers, important family commitments...
I know for a lot of kids who have parents taking care of them, it is great advice to "Relax! Don't worry! Just be calm! Go to the Bahamas! WOOOO PARTY"
Other people are too neurotic not to do anything, and honestly it could be a huge shock to go from binge watching Game of Thrones to studying 16 hours a day. Just because you study for 1-2 hours a day over coffee doesn't mean you're "ruining your last bit of freedom" - Many people already have a lot of commitments anyways and don't have the luxury of "just chillin'".
Disclaimer: I understand this might not be the OPs case, but keep that in mind when posts in the future like this come out. Some people just want an answer to their question. Not everything is so black and white. You can always be studying WHILE on the beach at the bahamas.
