I work hard in real estate, harder than most women half my age. At 67, I'm driven to succeed, so determined I've earned the nickname of "Barracuda" for my hard-nosed ways. I may be a senior citizen, but hardly look it, a lithe pounds on strong, five-foot-seven frame, muscular in the legs from years of running and taking care of myself. I went inside and noticed my bedroom door ajar, which was odd since I always closed it. I looked out the back door: My grandson Wally's bike was there.
