The Fountain of Youth Contains Grape Juice and Vinegar?

I play soccer every Sunday, and my body hurts when I start and my body hurts when I finish, but there's a twenty-minute window when I feel young again, but that twenty minutes cost me-- I'm sore for a few days after I play-- and the effects are both physical (I limp on my left ankle) and mental (kind of like Charlie in "Flowers for Algernon," it makes me remember that I was once young and fast and limber, but now I'm headed in the other direction and, sadly, I realize it) unless, and I still haven't tried it yet, unless the home remedy I just learned about is truly a fountain of youth . . . the recipe is one part apple cider vinegar to four parts juice (grape and apple) and you drink a few sips of it, chilled, every morning and then you're never sore again.
