My wife has a w pouch, one of the early ones from the 90s. She goes to the gym regularly and runs a lot on the treadmill. She only had one operation. In those days they did it In a oner rather than spreading the procedure over several ops.
It is legal to attack someone if you reasonably believe they are about to attack you. Beat them to the punch. For example if someone verbally threatens you it is advisable to hit them before they finish their spiel.
