Alex P. Keaton loves Bhutan

I've adored Michael J. Fox ever since he played Alex P. Keaton on Family Ties back in the day, and I've been saddened by his Parkinson's disease.

Recently he traveled to Bhutan, where he noticed a significant lessening of his symptoms at high elevations. In fact, he became so exuberant that he nearly fell off a cliff in his dashing about.

His documentary on the value of optimism airs on May 7 on ABC.
