If manipulators really had the powers claimed, they could win the lottery every week. I prefer to point out that they could also win a Nobel Prize for discovering fundamental physical forces hitherto unknown to science.

...it is a telling fact that, the world over, the vast majority of children follow the religion of their parents rather than any of the other available religions.

Five per cent vision is better than no vision at all. Five per cent hearing is better than no hearing at all. Five per cent flight efficiency is better than no flight at all.
