Martin Sheen became "fanatic" when his son Charlie was using drugs.

"When a life is at stake and it's your child, you become fearless in a lot of ways. I mean, you just become fanatic," the 67-year-old actor says in the July/August issue of AARP The Magazine. "Nothing ever gets done unless it's done by a fanatic."

Sheen, who portrayed fictional President Josiah Bartlet on NBC's "The West Wing," tells the magazine how he intervened to save his actor-son.

"The only way I got to Charlie, frankly, was because he'd skipped out of the hospital. I had to pay the bill," Sheen says. "In paying the bill, I got to see why he was in there. He'd consumed an illegal substance; he was on probation. ... This was a criminal matter. And so that was the wedge; that was the leverage I had. That is what I took to the court; that's what I took to the sheriff. It was the only way I got him."

The veteran TV and film star, who battled alcoholism himself, also turned to Alcoholics Anonymous to help his son.

"I got sober through Catholicism, through my faith," Sheen tells the magazine.


Highly educated Hindus

Among Americans of different faiths, Hindus, Jews and Buddhists tend to have higher levels of education than members of other religious traditions, and they are also the most likely to have a post-graduate degree; nearly half (48%) of Hindus, more than one-third (35%) of Jews and a quarter (26%) of Buddhists have a post-graduate education. Among American Protestants, members of evangelical and historically black churches tend to have lower levels of education compared with those belonging to mainline churches. For instance, nearly six in 10 members of evangelical (56%) and historically black (59%) churches have a high school education or less, compared with 42% among members of mainline churches. Catholics and the unaffiliated closely resemble the general population in terms of education.
