I saw Janie today at Holyoke Center and now I'm motivated to share my story.  When I last knew her I was not a biker.  I started biking from my home in Brookline to Brigham and Women’s Hospital which takes about 10 minutes due to the cost of parking there.  Eventually I started to really enjoy the ride and feel healthier.  I also work in Harvard Square but thought I was too old, it was too dangerous and too long a ride.  A young co-worker said those were all incorrect and I should just try it.  I was scared at first about the car traffic but after my first ride which I survived, I was just elated.  Now I ride all the time in all weathers except snow and ice on the roads. I feel so energized, I have also started to exercise more, my health has improved, I've lost weight, gained muscle mass and it turns out that biking to Cambridge for me takes 30 minutes, taking the bus or the T takes an hour!  Plus I save on the order of $20-$30 on parking.
