The only foolproof method I know:
a) Train daily for 3 months at short distance running. Try to achieve at least 11.3 secs for the 50 meter dash.
b) For the same period, eat plenty of hard boiled eggs, rice and other "binding" foodstuff. Avoid prunes, grapes, fibre and greens.
c) On a pre-appointed day that will be your Piles Liberation Day, take off your lower garments, all of them. Get ready, set, and start running like the clappers. Being "bound", the contents of your stomach/intenstines should be safe, but with luck you might leave your haemorrhoids behind.
