In the immortal words of the bard: This way lies madness...
Everything in life involves some level of risk: driving, walking out your front door, taking a shower, just existing involves a remote chance of getting hit by random debris from space, etc. Taken to absurdity, one could go to the extreme of spending one's life in a bunker Faraday cage with padded walls and a gas mask hanging around one's neck at all times in an attempt to minimize risk. However, I can't imagine that would be good for one's mental health, happiness, or well-being.
I think one has to become comfortable with accepting a certain level of risk in order to be reasonably content in life. Reasonable choices taking reasonable precautions seems the order of the day for most people.
As an aside, it does seem that "reasonable precautions" for my generation growing up is entirely unreasonable for the current kids. Things like playing in sandboxes now suddenly causes silicosis, 1 infant car seat now requires 3 separate car seats, and riding a bicycle now requires a helmet or the parents are negligent, etc. come to mind. It seems like "reasonable precautions" is a societally defined moving target over time
