Fresh Air on Four Corners

At age 66, Neil Young has taken the advice of his doctor and stopped smoking marijuana — though he's not "making any promises," he says.

The Canadian singer-songwriter and guitarist has a new memoir titled Waging Heavy Peace, in which he talks about his music, family and medical conditions, including polio, epilepsy and a brain aneurysm. In the book, he describes a particularly painful procedure he went through, which has since been banished.

Right now, as we near the end of the 2012 fall TV premiere week, there's a tendency for a sense of weariness to set in. So many of the new TV series are so bad this year, and not one of them is outstanding. It tends to get a little depressing.

But then you think about the rich bounty of returning series, and how good television drama has gotten lately, and there's cause to rejoice all over again.

I adore time-travel pictures like Looper no matter how idiotic, especially when they feature a Love That Transcends Time. I love Somewhere in Time with Christopher Reeve and Jane Seymour, The Time Traveler's Wife, even The Lake House with Keanu Reeves and Sandra Bullock in different years sending letters through a magic mailbox. So terrible. So good. See, everyone wants to correct mistakes in hindsight, and it's the one thing we cannot do. Except vicariously, in movies.

One night in 1984, British scientist Frances Ashcroft was studying electricity in the body and discovered the protein that causes neonatal diabetes. She says she felt so "over the moon" that she couldn't sleep.

By the next morning, she says, she thought it was a mistake.

But luckily, that feeling was wrong, and Ashcroft's revelation led to a medical breakthrough decades later, which now enables people born with diabetes to take pills instead of injecting insulin.

When Amy Adams read the script for Paul Thomas Anderson's new movie, The Master, she saw an opportunity to play a character type she'd never played before.

"Somebody who on the surface was very, very mothering, almost genteel, and then underneath, there was this boiling almost rage," Adams tells Fresh Air's Terry Gross.

After the global financial crisis hit in 2008, Pulitzer Prize winner J.R. Moehringer was so angry at banks, he says, he decided to write about the people who rob them — in the form of fiction, since he's not an economist.

"I thought it would be healthy to live vicariously through a bank robber at that moment that bankers were ruining the world," Moehringer tells Fresh Air's Terry Gross.

In his first historical novel, Sutton, Moehringer writes from the point of view of Willie Sutton, whom he calls the "greatest American bank robber."
