It's an old saying and it's very true. Many of us like dangerous things or even things that we take for granted that are not dangerous. As an example, walking. Simple, normal, done with very little thinking yet many people are paralyzed and never walk. How many times do we walk (or run) laughing and enjoying life? We are so fortunate for even things like the ability to walk or taste or see or physically feel.
Over the weekend a close relative had two strokes. She is at least temporarily paralyzed on her left side. I am laughing and walking and she can not walk right now. A laugh is not the same when a loved one is crying.
