Bicycle Helmets

To be honest, I always thought bicycle helmets were a waste of time - only needed as pretty useless protection against poor drivers on the road

Until a friend underwent open brain surgery

On a follow up visit she asked the consultant if it was OK to ride a bike

He said yes - as long as you wear a helmet 

Is that because my skull is now weaker from being opened up?

No - it's as srong as everyone else - which is weak - you should wear a helmet always when riding

Also ..... if you crash and hit your head - you should change the helmet, regardless of any visible damage - as sometimes the damage (saving you) is not visible
