Good.

Do you believe all points of view are equally valuable?

> in 2012 i owned a car that could run 100 octane fuel, and that was $9 a gallon. a few more octane and you get Jet-A minus the additives.

So? Diesel and petrol (gasoline) are different fuels. Comparing them by RON is irrelevant.

The perennial question.

Well, at least it’s spurred intellectually curious discussion.

My BMI is 28.7 at 181cm and 94kg at 45.25 years old.

Am I overweight, not far off obesity?

You probably wouldn’t say so if you saw me.

BMI is mostly only a useful metric when it is.

non-Exercise Activity Thermogenesis?

I’m a bit of a fitness enthusiast, but not enthusiastic enough to have come across all the acronyms.

> It’s pretty well known, in cycling at least, that hard interval training is super effective for untrained people or people coming back from a break, but the gains plateau relatively quickly, and the stress of doing this kind of work is hard to sustain for long periods.

This is 100% experience with both cycling and running, and something I worked out on my own early on, prior to the advent of smartphones and even talking to anyone who knew anything.

I enjoy sprinting, both running and cycling, but it’s mostly something I do to regain my endurance ability after a break. Two two weeks of high intensity interval training, and then I’m able to sustain moderate intensity jogging for 30+ plus again, or an hour cycling.

Can you clarify your last paragraph, looks like there’s a typo or grammatical error that states the same outcome for both arguments put forward in the preceding paragraphs.

> Which would ignore that jet fuel is going to be a multiple of the gasoline price.

That doesn’t sound right. If my Duck Fu is any good, jet fuel is currently going due US$3.00 per gallon, avgas (leaded petrol) at $3.30, and gasoline at $2.88 gallon.

There’s nothing much special about jet fuel, it’s just kerosene, same as RP1 (Rocket Propellant), heater fuel, and lamp oil you can buy from the hardware store, with a touch of something to stop it gelling at low temperature if I understand correctly, but also jet fuel tanks are heated if I recall correctly.

I believe standard diesel fuel will also works in jet engines, but kerosene is cheaper.

I’m not in the US, and if I understand correctly their gasoline (petrol) price can vary greatly from state to state, California being the worst? Is that right?
