Ask family members of someone with Alzheimer's or another dementia: Trying to talk with a loved one who doesn't even remember exactly who they are can be very frustrating.

But here at a senior center in Seattle, things are different.

On one recent day, 15 elderly people were forming a circle. The room is typical — linoleum floors, cellophane flowers on the windows, canes and wheelchairs, and walkers lined up against the wall.

Six months before the presidential election, the Florida ground game is already under way.

In political terms, the ground game is the process of mobilizing voters and getting them to the polls. And the first step is registering people to vote.

But in Florida this year, there are tough new restrictions on groups that conduct voter registration drives. The restrictions already appear to be having an impact on the number of people who are registering to vote.

You may think of surfers as slackers. But in Santa Cruz, Calif., they're city council members and business owners. And they're also conservationists — who just got their piece of the central California coast named a World Surfing Reserve.

Long before surf music topped the charts and long before surfers had crazy nicknames, surfers have been riding the waves in Santa Cruz.

Fifty years ago, Johnny Carson became the host of The Tonight Show. During his 30 years as host, he reached a nightly audience of 15 million people and became one of the most trusted and famous men in America.

But Carson was intensely private off-screen, and very few people — including members of his own family--really knew him. Documentary filmmaker Peter Jones wanted to try and change that. Once a year, for 15 years, Jones sent Carson a letter, begging him for permission to make a documentary on his life.

In the streets and public squares across Spain on Saturday night, the cries of a mass movement calling itself the Indignados rang out, railing against austerity measures imposed by the European Union.

In Greece the next morning, Alexis Tsipras, the head of a far-left opposition party, held a news conference to say he wouldn't join a coalition government that continued the path of austerity.

In 2002, Rafe Sagarin was working in Washington, D.C., as a science adviser. It wasn't long after the Sept. 11 attacks, and Sagarin started paying attention to the security measures on Capitol Hill.

"I'd watch these other Capitol Hill staffers and I noticed that they'd just put their hand over the keys in their pockets so they didn't have to waste 30 seconds putting it on the conveyer belt though the security screening — and that didn't set off the alarm when they did that," Sagarin tells host of weekend All Things Considered Guy Raz.

When you turn on the morning news in Zimbabwe — or the afternoon news, or the evening news — there's a virtual guarantee you'll hear about President Robert Mugabe, or even his actual voice.

Even when there's a song by the Zimbabwean group Born Free Crew, it features a voice-over of none other than Mugabe, who's been leader since independence in 1980.

Weekends on All Things Considered continues its "Why Music Matters" series with stories of music fans, told in their own words. Today's story is about Amy O'Neal, a choreographer who took on the challenge of dancing in complete silence.
