But if there’s a significant chance that it won’t do ANYTHING, well, damn, what a risk.
I don’t see hanging as being more likely to not work than hands on PE. Any form of PE has a chance of not working, and not working for you. It is just that hanging has a larger time investment to find out if it works for you or not.
If you have privacy, the right personality traits, and are sitting in front of the computer for hours every day, anyway? Suddenly hanging is a very viable alternative, and with no more task specific time investment than manual PE.
