I would rather go a week without changing clothes...and I'm fairly certain I have in the past! We camped our way around the Eastern half of Australia a few years back and I often found myself putting the same clothes back on after a quick shower or wash - it didn't really matter given we were in a different town each day - no-one to notice us wearing the same thing day in and day out!!
Got no choice when out on exercises in Army! Showers everyday, depends where you were, but no clothes change for a week. This is in January in Qld, so hot! By time got back to home base, uniforms etc., could walk to washing machine by themselves! They were 'ripe' & then some!
I’d rather go a week with out…changing my cloths. I gave up a Zimbabwean holiday in ’91, because I was told I wouldn’t be able to have a shower for 4 days, as ‘we’ boated down the river, sleeping in a tent at night.
I shower after my morning walk, then have another 1/2min shower just before i go to bed, even if it’s in the early hours of the morning!
