Somegirl's thread "On Fear" brought up personal fears I have about walking alone.  I don't know if the fear is rational or not.  I live alone, and so there wouldn't be anyone to miss me if I didn't arrive home in a reasonable time.  Also, I'm not as fit as I once was and worry that I wouldn't be able to run away if I felt unsafe.  

I'd love to be able to walk on nature trails, but am too afraid to go it alone. 

So I have decided to take tennis lessons this summer and join a tennis club.

Do any of you play tennis?  Is it fun?  Did you meet lots of interesting people like members of the opposite sex?

Is tennis good exercise?

I just spent two days at a workshop devoted to creating exercise programmes for seniors.  I'm pumped.  Can't wait til Monday to start implementing some of the ideas.

But the single most important thing I came away with from this workshop was the importance of activity in promoting a healthy long life.  I always knew this based on the seniors I have had the privilege of knowing but the past two days reinforced this anecdotal evidence with research.
