Arwa Gunja here, wrapping up the day’s production.

Tomorrow we are going to lead the second hour of our show with a story about possibly expanding the role of nurse practitioners. Twenty-eight states are considering giving these nurses with higher degrees more authority, including prescribing narcotics. This is due to a shortage of primary care physicians. We’ll hear from a doctor who is against this expansion and a nurse practitioner who says the expansion would benefit patients and pocketbooks. It is cheaper to see a nurse practitioner and often, they have more time to spend with patients. But some doctors argue it could put patients in harm’s way by putting their care in the hands of a less qualified medical professional.

And today, the Library of Congress announced they will start archiving tweets going all the way back to 2006 when Twitter was started.  This means that along with history books and great works of literature, tweets will live forever in our nation’s most prestigious library. We’ll talk with a "library and archivist groupie" about how this changes the way we look up history. If you’re on Twitter, will this change the way you tweet? Are there any tweets from your past that you would want to be archived in history? You can call us at 877-8-MYTAKE, leave us a message on our website, or better yet, tweet it.

Anna Sale here on the day shift.

Leading up to April, we've had a few really interesting conversations about taxes. We talked about Americans' mixed feelings about the IRS through history, and learned how Mexican artists can pay their bills by donating work to the government's collection. Tomorrow, when the deadline hits, we'll look at the personal experience of paying your tax bill. We want to know how it feels to see your last year boiled down to a list of numbers and a few key words. Did you move? Sell a house? Lose your job? Lose a spouse? It's all in there. We're reaching out to a few taxpayers and a few behavioral economists to get a more intimate look at this rite of citizenship.

And as many of you are busy filing your tax returns electronically, we'll talk with a blogger who has given up the internet as an experiment. This doesn't just mean he's missing out on Twitter and Facebook updates. He's using mail and the phone to work with his editors. And reader comments? They're coming in via the postal service. We'll talk about how this chance of pace is changing his approach to his work.

We'll also look at the connection between age and wisdom. But we want your thoughts on it now. Do you think you're wiser now than when you were younger? And do you think older people are wiser than you now? Researchers at the University of Michigan investigated whether older people are more likely than the young to accept differences in value systems, deal with uncertainty and accept change. The conclusion? In effect, age does contribute to wisdom. Start the conversation now and tune in tomorrow.
