I was lazy as a kid, always preferred lying around reading to running and jumping. As an adult, there was no TIME to be lazy! Working full time, raising kids, going to school, keeping house, yardwork, you name it. Some days I never sat down until everyone was in bed. Still got and stayed fat, though. Now, there was a lot of MENTAL laziness in my adult life. It's easier to do 7 hours worth of things in 3 hours when you don't have to cook. Picking up prepared food and taking it home to feed us all was NOT a necessity, that's what I call laziness. I hated to cook, didn't really feel comfortable with it, didn't really know how, and we had to eat. . .so that's about all the laziness I'll admit to.
