Essentially nobody under the age of 50 dies, especially in the western world: https://ourworldindata.org/grapher/number-of-deaths-by-age-group?stackMode=relative&country=OWID_WRL~European+Region+(WHO)

Having learned this lets me quickly resolve thoughts of “what if I die” or “what if this person who is important to me dies” because I can reasonably predict whether that death will happen soon.
