But you wear seatbelts, live in a home that's passed safety inspections, but medicine and food from reputable sources and manufacturers that are inspected and regulated. Clearly there are circumstances where you go the extra step and have decided 'well no reason to tempt fate'. I assume you go to the Dr if you have an infection.
I'm glad you don't live in fear of killing a kid or someone you know that can't be vaccinated, but
that doesn't mean you're not putting them at risk whether or not you personally fear it. How awesome for grandma or the CVS cashier's 8-year-old that you have faced your mortality and are aware that you can't fool mother nature, so why bother fighting it so hard, eat drink and be merry for tomorrow we die, and if it takes someone else, well, at least you didn't have to care about knowing them personally.
The unafraid: a fratboy driving recklessly on the highway, weaving through cars at 30 over the limit, bemoaning how people get so scared for no reason, can't they see he's got it under control and is a good driver?
