Just returned from a holiday in Borneo looking for orang-utans. Tubing on the river through the jungle with monkeys cavorting in the trees above made me feel young again. Laying in a lorry tyre, rifting along with the current, a few fast bits to add excitement and no need to worry about stiff joints, etc. Brilliant! Can’t wait to do it again and it’s made me look at other new things to try. (Preferably sitting down things!)
