Our energy is spread thin more often than not. It is what it is. Long ago our energy was used to hunt, gather, build, repair – basic survival before civilized society. We did not need to exercise long ago because simply surviving the day was more than enough exercise.
Now we have first world challenges. But without exercise first world predators no one talks about are always lurking. Busy schedules. Competing priorities. Exhaustion. Excuses. Apathy.
