“Just remember, once you’re over the hill you begin to pick up speed.” — Charles Schulz

The trick is to defer rounding that hill into decline for as long as possible. My personal goal is to be a fit and witty centenarian. Whether that’s in the cards is up to fate, but we all ought to have goals in life, shouldn’t we? Prolonging the active, healthy and vibrant years seems as worthy a goal as any.

Those people who say it’s better to burn out than to fade away forget the third choice: living a fit, balanced life for as long as we can keep the party rolling. Good habits carry us higher up the hill, bad habits make us round the top more quickly than we’d want. Reckless behavior makes us stumble before our time. We know all of this, we just need to look up now and then to see what we’re straying into. When it comes down to it, we are what we repeatedly do, as the saying goes.

“Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree.” — Martin Luther

As a gardener, I see the parallels to living a good life: Get out there rain or shine, ensure that the roots are well fed, nurture the good and weed out that which will create problems later, ignore the rest. And most important, keep investing in the future. We are tending to a garden we may never harvest, but there’s magic in the act of tending it anyway.
