My cute little boy is taking care by a babysitter during weekday. She is a married lady and about 60 plus years old. There is one time, she told me that she used to exercise daily by fast walk at the kitchen, then I was shocked, and asked her how she exercise when there is no treadmill equipment available. You know what she told me? She said I just do a fast walk at the same place as thought there is a treadmill. Wow, she reminded me of what I heard before last time, when it is a must, we will do whatever it take. And my babysitter is a good example.
