You can check this out about David Wheaton,
www.davidwheaton.com like socket said, he's doing a lot of motivational speaking and is really doing lots of religious activities and projects as well.
For those asking about Slava Dosedel, I remember in the late 90s when he was playing and was one of the dangerous floaters on the tour, I heard that he was doing acting in his country which was the reason for his limited schedule.
