the roms megathread linked in the OP links to myrient for a lot of categories

im pretty scared of kangaroos, half of them are like cute little rabbit dogs and then there's randomly some of them that are like, steroid-jacked dog murderers with a secret tailspring disemboweling kick attack, the fact that the scary ones exist and are the same species as the cute ones means that you can never be sure if interacting with the cute ones will attract the ire of the scary ones. their physiology is way different from other mammals, if a kangaroo invented a car it would not have wheels but gigantic spring loaded skis and you would pilot it from a dark and warm mucosal sac. i actually think that the tall aliens in halo are probably canonically kangaroos

on average in the u.s. a 65 year old man will live to 84 and a 65 year old woman will live to 87

the likelihood of making it to at least 90 are 30% for men and 40% for women

the likelihood of not living beyond 70 is 5-10% for men and <5% for women

there now we're all longevity literate
