Whenever I hear someone say they don't have time to work out, I think of an old Saturday Night Live skit where Jane Fonda was trying to convince an older woman who was cleaning a building and had children at home that if she just managed her time right, she could do aerobics. It was funny because people who work out can be myopically, ridiculously evangelistic about exercise.
I'm not one of them. There ARE a lot of people who don't have time to spend an hour at the gym. I have students who are paid to spend eight hours on the job, are taking my online class to earn a graduate degree, and have small children at home. I don't know how they do it. Wait, I was doing the same thing myself 15 years ago! I don't know how I did it. I was younger, that's all I can say. I didn't spend time at a gym during those years, but I did find ways to exercise. I used to run to the grocery store with my daughter in the stroller and the dog tied to the handles, thereby accomplishing four things at once. I'm so glad I'm not young anymore.
