i was a 100 hours a month pio in the UK in the late 60's--from age 18 to 21. my time included lunch breaks--travelling from a first call--even if no-one home--to the group meet up. visiting the elderly in the cong--doing odd jobs for them----and the sick. lighting the coal burning boiler at the KH in the winter.
all a total waste of time. just a social thing really--there were quite a few of us. i never bought anyone into the cult. quit at 23.
