drop out at 75 and "Let nature take its course"?
As for Dr. Emmanuel, he raises interesting questions as well...it is true that a LOT of $$ gets spent on HC for seniors (illnesses and frailties come with the territory) and the actuarial charts don't lie, the "ROI" isn't the best...which is why many seniors ('moi' included) sign 'DNRs' to forestall 'unreasonable' measures being taken. Nonetheless, in our own extended family, there are numerous examples of very active and treasured members who have made it to their mid-to-upper 90's, and when they get sick, we're very, very happy that they have the medical care to keep them with us.
Perhaps as a slight aside, I feel blessed to have learned a great deal from them in many conversations over the years...through their 80's and 90's...they've been more cogent and wise than many younger folks I've come in contact with, so if I had to perform a triage on who to protect from serious illnesses, I'd have to add in a few more caveats than just age...get where I'm going on this?
As for "Slippery Slopes", it could be argued that arbitrarily denying HC to persons simply due to age on an actuarial chart could lead to similar denials for younger people with "actuarial limitations" as well...you know...like "pre-existing conditions"...what's your stance on that?...after all, they can be such a drag on profits.
