The pop-up menus also have a very fast transition (compared to many websites) which aids in the feeling of snappiness. I don't know why so many sites insist on very slow transitions
Frankly, I think most doctors aren't qualified to make such a decision by virtue of lacking PhDs: their expertise is in clinical care, not in evaluating research.
Sure, but the doctor doesn't have to do much research in this case. This is front-page news in the NY Times. And about "every single medication": this is the only approved medication to delay clinical decline due to Alzheimer's. And there are only a few medications to treat symptoms.
I know this isn't a perfect world, but it doesn't seem to be asking a lot for a doctor to know this. (Especially for a drug that currently costs $56K/year and presumably will cost more next year.)
The Space shuttle SRBs were somewhat re-usable while the external tank (arguably similar to the F9 second stage, except that it was used for the whole flight) was expended. The external tank was ~30,000 kg dry mass and was expended with each launch. The system could deliver ~27500kg to LEO (assuming the SRBs are fully reused which is not entirely accurate).
Falcon 9 FT Block 5 second stage has a dry mass of 4000 kg which is expended. It could deliver ~15,600 kg to LEO with first stage reuse.
