I'm desperately trying to fit exercise back into my life, and the only viable way I can see to do this is to use my lunch-time to go for a run twice a week. I really can't be gone for more than an hour, and I can get changed, go for a 30 minute run, have a quick shower and get dressed and back to my desk in that time, but I definitely can't wash and dry my (below shoulder length) hair. Is it really grim to run and sit with the sweat in my hair in the office all afternoon? I think if I tie it up in a tight bun while I run it'll look ok, but I'm worried it might be socially unacceptable, so thought I'd put it to the famously sensitive noses of the vipers...
