10. Fatigue
DC ComicsReading comics requires a pretty hefty dose of suspension of disbelief, accepting a lot of feats and powers which routinely shatter every rule of physics in the book, but seriously, Batmans sleep schedule is totally whack. There is no way there are enough hours in the day for you to pump enough iron for all the thugs youre going to beat on tonight, keep up to par on over 100 different martial arts, do background research on whatever the Jokers doing next week, tinker with the latest gadget from Lucius, hit Crime Alley till dawn, and still expect to keep up that genius level intellect and killer reflexes off of a bat-nap. In fact, it seams like eating and sleeping are activities that only occur when Alfred, the true master of Wayne Manor, makes him attend to them. https://www.youtube.com/watch?v=eCTngb7hJGo Its not like either of these are exactly a chore either. Batmans supposed to be the peak of humanity, a world-class athlete and a master tactician. You know what both of these groups of people do in order to retain their skills!? They sleep, they eat, they rest up, and then perform at their peak when its go-time. It doesn't what kind of meditation secrets you learned from Lady Shiva or this awesome herbal remedy that Poison Ivy gave you for a rejuvenating feel to your midnight prowl, you cant fight what the body wants, Bats.
