Where we place resources on security issues is a matter of value systems. A pedestrian is 10 times as likely to get injured as a car driver, assuming you don’t die first from falling telephone poles, break your neck on a wet stairway, get electrocuted while typing (because your toe touches the outlet), accidentally strangle yourself in bed, have a truck come through your wall, have a neighbor’s TV set fall out of the sky on your head, get impaled by a falling tree branch, die of food poisoning from an ice coffee, have a tiger appear in your bedroom closet and kill you (escaped from the zoo), have a polar bear come out from under your bed, or have a passer-by’s umbrella accidentally cut your carotid artery and make your neck spray a fire hydrant of blood, dying 10 seconds later.

But of course, we are 10 times more likely to spontnaeously develop a disability than die accidentally. We are extremely likely to develop at least one disability before we die, to go deaf from listening to too much loud music, go blind from glaucoma, become clinically psychotic from Huntington’s disease, require the use of a wheelchair, develop diabetes and get at least one foot amputated, develop acid reflux that makes us puke hot acid all over everything, develop a tumor in our nose that requires the nose to get amputated, develop blood clotting disorders that make us go around with black-and-blue skin, acquire a staph-A infection that requires extensive amputations, spontaneously develop multiple sclerosis despite no such family history, or a million other debilitating medical conditions, for which medical science currently has no cures.
