When I was doing the bol thing on a few acres I had one of those camping crappers with me, I tried squatting over a log etc but my knees wouldn't take it. When the little tank got half full, couple of weeks, I'd detach it, carry it off into the bush 200m away and pour in into a natural hole under the edge of a log. A lifetime spent not squatting takes it toll. I bet there isn't a Jap that can't do it easily, at any age.
