2021/12/21 The rebound effect of most safety precautions is statistically less than the protection it offers. Seatbelts and airbags make some people drive faster and with a little less caution.

The vaccine for COVID19 makes some people feel comfortable attending parties with unknown elements. Proximity to medical facilities makes some people more risk friendly in general. At some point cigarette filters made some people more comfortable smoking.
