As a current guppy cap and former wbfo I’ll tell you why. Because many people (myself included) feel like hammered horseapples after each and every oceanic crossing. Took me a whole day to feel human again. I don’t sleep well in the bunks, nor do I do well trying to sleep and wake up 10 or 12 time zones away. That’s the beauty of this place, all the options. And yes, I know how to manage, diet, exercise, alcohol intake etc. just the way it is.
