Here are traffic deaths by age group: https://www.cdc.gov/mmwr/volumes/68/wr/mm6806a8.htm. Let's pad those numbers up by a significant amount and assign 20 per 100,000 from birth, and remove those deaths from the life tables (ie let's say noone dies from traffic accidents in the USA). That still only lifts life expectancy by 1 year (from 78.6 to 79.6)
You can keep adding other parts of accidental deaths but: 1) they don't fit the story of USA dying more from driving 2) the leftovers are already below the accidental death rate from countries with much higher life expectancy 3) a big chunk of the rest is accidental falls which predominantly affects very old people so doesn't have a big impact on life expectancy
Also, I work in genomics and am a 23andme customer/product (although I was the latter before I the former became true).
Do you happen to know if rs1229984 is linked to any particular group that could make this result problematic? I noticed that the paper mentions that "There was also some evidence for a difference in years of education, and, while the size of the effect was small, this requires further investigation." That sounds like a decent-sized red flag.
Ad-libitum feeding is not force feeding. Noone goes and shoves the food into mice. The food is just available.
Also, CR has extended lives in many species, including dogs (see https://avmajournals.avma.org/doi/abs/10.2460/javma.2002.220...), not just mice.
EDIT: talking about Sprague's implementation btw, not necessarily OPs.
