You should be. The little things you do make a difference. You know this because you see the risks others take. For example, take that big guy riding that big bike. He is decked out in all the fancy motorcycle gear. He is feeling good. His body is well-protected.
His head? Not so much. He is not wearing a helmet. Where is the logic in that? Your brain is the most complex organ in your body. In a motorcycle crash, your chances of survival diminish if you are not wearing a helmet. And if you do survive, what are the chances you will suffer a traumatic brain injury that will impact your quality of life? Long-term care is a real possibility. That means somebody else could be providing assistance, including changing your diapers.
