Thanks for your responses...
Thank you both for your replies. My sister is in very good health, but she is also very petite...about 5'1" and maybe 105 lbs? She is 4 years older than me. I wondered if size was also an issue to consider? I hate to keep thinking of all the reasons she won't work, but I'm trying to educate myself just in case.
