I'm in my mid-40s. For about 15 years, I sat at a desk writing code and slowly dying. Three and a half years ago, I started running three times a week. Then, a little over two years ago, I switched to a standing desk. I've never looked back. To avoid stiffening up, I play music (usually progressive house or something similarly rhythmic-but-not-too-distracting) into noise-cancelling headphones and let the music move me. Because I'm not standing still, I don't experience lower back pain, stiffness, soreness or anything else. If I had to go back to sitting now, it would kill me. [] NB I wrenched my back last autumn by twisting in a funny way while painting a ceiling with a roller on an extension pole. After a couple of weeks of Advil and an aggressive regimen of back exercises and stretches, my back pain was completely gone and I feel better than ever.
