I once went to a 3 week camp where the showers broke. Hence, no showers for three weeks.
My parents arrived in protective suits to pick me up. It was nasty. The hair stops being greasy after about a week, but the dirt and the smell is just disgusting. Long story, short is that it was miserable, and I had like, eight showers the day I came home.
I shower every evening, though, unless I'm off work and then I may skip a day because I won't be icky and sweaty.
I usually shower every three days or so, but the longest I've gone without showering was 2 weeks. :o It was horrible. :( I'm trying to take showers more often, though, but sometimes I just don't have the time. (I can take up to half an hour in the shower, but my usual is 15 minutes.)
I normally shower once a day.
Every other day is pushing it - I feel the world has turned against me and may send out ninjas to kill me in order to remove the source of terrible stench.
I shower erratically. There is no consistency what-so-ever, but I don't go more than 3 or 4 days. lol
The longest I lasted was 1 day. Its the max I can go w/o a shower cause the weather in my country is horribly hot :l
The longest...5 days without taking a shower. There were problems with my appartment, and water didn't come to us, so yeah. :x Now I take a shower everyday. xD
