I don't know anything about police officers (other than that my neighbor is one). Still, I'll take a stab at offering some ideas that may be of help.

My first guess is that the retirement statistic starts with the old adage: use it or lose it. With nothing to do, especially nothing that they perceive to be as important as protecting citizens, their skills (and health) can quickly wither away. The first thing I'd recommend is to work on recovering health. There's an excellent book called Somatics by Thomas Hanna that offers excercises designed to preserve and recover one's mobility throughout the later stages of life.

After recovering mobility, you may want to check out some of the weight lifting works by Pavel Tsatsouline at www.dragondoor.com. Lots of military and law enforcement personnel frequent the discussion board there. There's even a guy who re-started lifting weights, using Pavel's techniques, at around age 67. He became a top powerlifter for his age group by 69. Pavel's two most popular works are called Power to the People and The Russian Kettlebell Challenge. (I have Power to the People on video and it really is excellent.)

Another good book is the recent How to Get Lots of Money for Anything Fast by Stuart Lichtman and Joe Vitale (which you can learn about at www.getanythingfast.com). While it is by far the most atrocious title for any book that I own, the book does present some very good tools to set and accomplish (and discover) one's goals.

Hope those are helpful.
