at least twice a day, often 3 times. Once in the morning, for like half an hour because it wakes me up, which you need at 5am, trust me
once when i get home from work, cus I'm all sweaty haha. and quite often before I go to bed, because it helps me sleep a little better, I have real problems with sleep, especially in the summer.
Also, I dunno if peeps rememeber, there was a thread about washing hands a little while back. That was before I started working as an engineer, I said that I never washed my hands, at all. I've gone from washing my hands the least on the website, to washing quite definitely the most
. Like 10 times a day or something, that's if we haven't been using chemicals!
