Sure. Sounds like something I would totally believe. I don't actually know though. this shit is gay.
A 65 year old friend of mine had his hip replaced last year and the doc wanted him to use the walker for the first 2-3 weeks of recovery though my friend felt he didn't need it ... and there were exercises to make sure he had the best recovery. I'm sure it's SOP for hip replacements. Nancy's only other option would be a wheel chair (that would make her look "weaker" than using a walker).
It's looking like a geriatric ward.
