I remember getting so much crap from people ages ago over this topic XD I don't shower every day, I do it every three days. I don't engage in physical activities, I don't need to obsessively clean myself. My hair has been much nicer for it since it's often awkward the day after a shower because I shower at night and if it's a little damp when I go to bed it seems to really go off on one in the night and refuses to budge in the mornings I'll shower the night before if I'm doing anything special the next day, too.
We simply DON'T need to shower every single day, I honestly don't buy into the whole 'shower twice a day' thing.
I'm the exact same way. I always shower at night, usually an hour or two before I go to bed that way it has time to dry and isn't all over the place in the morning. I also only shower once every two to three days and never have my friends or anyone complained about smell.
At everyone who called me crazy for taking a 40 minute long shower: You've clearly never had one, they're amazing.
I wish I could take a 40 minute shower sometime.... But I live with three other people, and only one bathroom. EVERY time I'm in there for more than 20 mintues in the shower someone ends up banging on the door yelling at me to hurry up.
