Thank you, Patricia Cohen! Aside from the creaky joints and chronic conditions that attend the downhill side of life that I daily feel, your article reassures me that these are just the pangs and pinches of ‘middle age.’ Your findings embolden me to say that the SA might survive the decade and beyond, without, I might add, drooling, delivering drivel, or dying. I’m forever thankful. And your conclusions couldn’t come at a better time. Sixty is indeed the new forty! Now, can you just convince my 16-year-old daughter that I’m not a doddering old fool?
