Help yourself be younger?

Apropos the lively commentary this week on my September 6 web log, "Exercise: For your health, grin and bear it," a well-exercised, younger friend has recommended a book, Younger Next Year, by Chris Crowley and Henry S. Lodge, which promises that you can

Turn back your biological clock...become functionally younger every year for the next five to ten years, and continue to live like fifty-year-olds until well into [your] eighties...enjoy life and be stronger, healthier, and more alert...stave off 70% of the normal decay associated with aging (weakness, sore joints, apathy), and...eliminate over 50% of all illness and potential injuries....

    Possibly a bit too good to be entirely or literally true, but, still, my friend avers that

because aging slows reflexes, falls and injuries are significantly less likely as people age when they eat properly and exercise regularly—30-60 minute daily cardio, 2-3x weekly weight-lifting, also balance and flexibility exercises. Staying fit and strong improves reflexes and reaction times, which prevents, avoids, or minimizes accidents. That’s only one of many research-backed facts the book explains, also that at least 50% of most of what we consider “normal or accelerated” events in aging are actually optional—meaning, a result of lifestyle or choices, not predetermined by genetics.

Okay, folks hit the gym! I'm going today myself, and have been doing the "2-3x weekly weight-lifting" since April. I feel younger....
