Phhhhtttt, next you'll tell me the $25K 4k TV I bought in 2012 can be bought by the masses for next to nothing.

That's great if the item/service in question can be mass produced.

How much has the cost of a heart transplant gone down since its invention in 1967?

Depends on what country you're looking at.

Which a cure for aging would be.

How would we know that before it exists?

Because for it to qualify as a cure it must be mass producible. If it only works on one person, you haven't cured aging, you've merely repaired a body.

Realistically though, we have a pretty good idea of what we're looking for. We don't know the exact combination of chemicals that cures aging, but we know it's going to be a combination of chemicals, and we know we can mass produce those.

It'd be great if something as simple in mechanism and production as vaccination and vitamin D turned out to be the key to longevity. I tend to doubt it, though.

I get a med that's $18k every three months, for a mililiter of fluid. I wouldn't have a hope of paying for that without health insurance, and I'd expect health insurers to be resistant to covering mega-expensive life extension therapies.

Is your disease uncommon?

Generally, the more common diseases are cheaper to treat, because the burden of development, IP etc. gets spread across more people.

Medications for ubiquitous stuff such as high blood pressure tend to be comparably cheap, unless they are a fresh novelty. And aging is even more widespread than HBP.

> Is your disease uncommon?

Estimated at 2-3% of the world population, so 100M+ people.

So is the treatment something highly unusual?

I am sorry to be prying such information out of you, but things with such a cost label tend to be very high-tech (e.g. tumor-invading lymphocytes etc. that need to be cultivated for each patient separately, which cannot possibly be cheap).

It's a monoclonal antibody.

I suspect it'll look cheap in comparison to life extension treatments.

That's because monoclonal antibodies are targeted to a very specific protein. Polyclonal antibodies which can be used more generally are much cheaper. You're paying for the purity, not the substance.
