I am in my 60's and she still rocks it better than I do!  I think the only problem she has is heels....the older you get, you can't do the heels.  So take note when you see her, she probably has ugly flats on.  (Over 60 it you have osteoporsis, you don't want to fall and break a hip or anything in the leg region...bitch to fix and hard to heal)
