I envy kids, they actually tire themselves to sleep.
When I look at kids on the playground or just walking along with their parents (literally running to catch up), they seem so full on energy and they actually don’t mind getting tired. They know when they finally do get tired around they would be carried. As we grow old, we are so scared of tiring ourselves that we just stop having fun. We stop doing things that would tire us. It makes me sad. Remember, kids sleep peacefully because they are tired to sleep. They don’t sleep because they need to get up next day for work. Sigh. I miss being a kid. Kids are lucky.
