I've been a cyclist for seventeen years.  I've fallen exactly once, and
that was because the quick release on my rear wheel wasn't properly
tightened.  Anyone who knows how to ride a bike isn't going to go around
falling off all the time just because they're overweight.  

Stop trying to scare people out of exercising. It's not as if you
actually know what you're talking about - I mean, you don't acually *do*
any kind of physical activity, do you?

My daughter has rubella syndrome.  I contacted rubella measles in the second
month of my pregnancy.  This was a few years before the measles vaccine.
She has some motor coordination problems from cerebral palsy, mild mental
retardation, austic tendencies  and a severe hearing loss.  She's now 41
years old and functions quite well.  She has a job, rides the bus to work,
etc. About the only thing she can't do is roller skate - she just didn't
have the coordination for this.  Her brother and sisters tried to teach her
but she never got the hang of it.

She likes biking but was a little wobbly on the starting and stopping.  The
bike shop replaced the seat stem on her Giant hybrid and positioned the seat
as low as possible and she's able to reach the ground on tip-toes while
seated.  We tried one of the flat-footed bikes at the shop and she loved it.
I plan on getting her one next month before biking season gets into full
swing.  She and I usually include some bike riding on our vacations.  She's
rode the Chesapeake Bay Bridge with me twice.
