That car with the poor brakes, and all the other unsafe conditions, isn't unsafe at all until someone starts to use it. It's the act of using that causes the accident. Oh sure, the car was at fault, but the driver of that car was the ultimate cause of the accident. You will find many unsafe conditions in your daily life, but most of them become truly unsafe based on your own actions related to them. There's never a total absence of risks in our lives.
Risks are voluntary actions and can be managed.
Emergencies can be met and handled, but it takes know how and constant awareness. What you can't prevent, you can usually compensate for or protect against. The public category excludes motor vehicle and work accidents in public places. On the average, there are 10 accidental deaths and about 1,000 disabling injuries every hour during the year. About one half of the deaths occur in motor vehicle accidents while about one third of the injuries occur in and around the home.
