Darin,
Happy Birthday you ol' dog! Now that you're over the hump, the sailing will be smoother. Instead of worrying about your age, you stop counting. Watch out, though...it will appear that God has accelerated time for you, so that by the time you add another 20 years, it will seem like only 10. So, get those fender flares out and put 'em on!
"Never put off until tomorrow what you can do today". Ben Franklin
