You can change the world if you can get even a few percent of the general population on your side at the beginning - many of the most successful advocacy campaigns of the 20th century started in the hands of a dedicated minority. Bearing this in mind, look at this recent poll reported in the Poughkeepsie Journal: "In the poll of 1,000 adults, health tops the list of fears about aging; it was listed by 78 percent of women and 68 percent of men. Other fears include the possibility of 'losing the ability to care for yourself,' cited by 75 percent of women and 66 percent of men, and the loss of mental abilities, 73 percent of women and 65 percent of men. ... On average, people become "elderly" at 71, the poll found, but except for the 7 percent who say they want to live forever, the average desired life span is 87." Everyone cares about health, but a sizable minority care about radical life extension, it seems. Good news.
