I'm not justifying their "boo science, yay debauchery" line of thinking but let us look at the numbers (because I'm curious): This is for the US, from CDC data, so probably 30-something percent depending on how many were between 60 and 64: >Totals For 2010: 2,468,435 people of all ages died. About 11.9% aged 25 to 54. 24.5% aged 25 to 64 https://modlinlegal.com/blog/maybe-i-just-won-t-plan/90-the-odds-of-living-to-65.html https://modlinlegal.com/blog/maybe-i-just-won-t-plan/90-the-... And this https://data.worldbank.org/indicator/SP.DYN.TO65.MA.ZS https://data.worldbank.org/indicator/SP.DYN.TO65.MA.ZS shows numbers kinda all over the place depending on country, depending on where the person is from it may very well be that the majority die before 60-65 in their country. Angola, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, both Congo, Cote d'Ivorie, Equatorial Guinea, Eritrea, Eswatini, Gambia, Guinea, Guinea-Bissau, Haiti, Lesotho, Malawi, Mongolia, Mozambique, Namibia, Niger, Nigeria, Sierra Leone, Somalia, South Africa, South Sudan, Togo, Uganda, Zambia, Zimbabwe all appear to be under 60% chance (one or two may be at or above, I made the list quickly) of making it to 65 if I'm reading that table correctly. So, that's about 679 million people using 2017 numbers found via Google so not even 9% of the global population but still, that's roughly a 1 in 12 chance they are from a country where death before 65 is a thing for 40-60% of the population. Also TIL Nigeria has 191 million people!!! Wow, I would have never come close to that if told to guess.
