Broken Helmet

Went to the "I don't want it" yard sale Saturday.
To fill out my golf bag, I got a rock club for $1.00.
Put it on my bike (two wheel shopping cart.)
Getting off bike, tangled my foot on golf club.
Fell over backwards and hit my head.
Broke helmet. Head was protected and is OK.
In the melee, lost my valuable Gatorade water bottle.
New helmet and a new Gatorade will cost much more than the golf club.
It will still be much cheaper and less fuss than brain surgery.
