Many of my friends initially scoffed at the notion of an adult stroller, and not a few even doubted my sincerity. After all, I am a healthy, active 46-year-old man, married, with a wife and two children both of whom are grown or at least in school all day, as far as I can tell. I still enjoy walking, and I try to get a few runs in a week on the treadmill at the gym. But I love my adult stroller. It’s one of those things that helps me cope with my career and my life, both of which are, to say the least, hectic. If people ask me why I use it, I tell them I do it for me.
