I completely severed the tendon in my right hand middle finger and went to the er where they stitched me up and told me to contact a hand surgeon. Two days later the orthopedic hand surgeon told me that tendons die very quickly so he tethered some kind of cable to each end of the viable tendon and it worked. I have 80% usage of that finger but it took several years to achieve that.

They are more efficient, you are just missing some variable. The 2003 Accord curb weight was 2989lbs while the 2023 is 3239lbs. The 2003 Accord horsepower was 160 while the 2023 Accord have an horsepower of 192.

So the 2023 20% more powerful, weight 8% more, but is 11% more fuel efficient than the 2003 Accord. So the 2023 engine is much more efficient than just 11% since it have more power and it need to power a bigger car. If the 2023 Accord would have the same weight and power as the 2003, the engine might be like 20-30% more efficient (I don't know the exact number just a guesstimate)

Internal Combustion Engine by their nature is pretty inefficient. You can explosion happen to push piston, so obviously a LOT of energy will be lost in heat. There is just no way to get around that. We are getting better, but the ICE is a very mature technology, improving the efficiency is harder and harder to do.

>why haven't gas powered vehicles gotten that much more fuel efficient??

Petrol engines have. e.g. The 1 litre, 3-cylinder Toyota engine has been available in various Toyota, Peugeot, Citroen, Daihatsu cars for 20 years or so and will easily return 60 mpg.

You just don't see such 'city cars' in the USA because no red-blooded meat-eating christian would buy such a silly little vehicle.

Well the truth is, they have. It’s not night and day, as there are engineering and cost concerns that come with chasing improvements, and there IS a limit to how much power you can get from an ICE, but they are improved. But most of the improvements so far are weighed down, literally. Newer cars ar heavier, with more power output, and more features, and that all brings efficiency back down. All manufacturers could have 50mpg cars out ther tommmorow, but that’s not what the market wants.

Just fitting a cat doesn't bring the emissions into that range for the ULEZ.

And the range for MOT and ULEZ are different, otherwise every car on the road would be able to pass through the ULEZ, wouldn't they?

The ULEZ is a stricter set of measures for the given area, and that means that some older cars - even those with cats - won't be able to pass under that bar.

Same way that for years diesels would have passed, but since we realised what their ACTUAL emissions are, they don't qualify.

It's to do with actual recorded emissions, not age or technologies involved.

When you have a home game you get the following:

  • You spend the night in your own bed. And you can spend time with your family
  • You can relax and drive yourself to the the arena at your own leisure.
  • Staff and teams are familiar with the souroundings.
  • You are better supported by the extended team staff.
  • Home locker rooms and facilities are well staffed and emanates are everywhere.
  • You will have the support from the home fans.

when you are traveling team.

  • You usually need to travel the day before, sometimes two days before. Planes, trains, buses.
  • You are spending a night in a hotel in places you are unfamiliar with..
  • You are on a strict schedule because you are traveling as a team.
  • you are getting to the stadium where you might not know where everything is.
  • Your locker room is likely the bare minimum the home team needs to provide to you.
  • you have to deal with a hostile crowd.

​

A funny story about this was when teams came to play the Boston Celtics or Bruins at the Boston garden. The Boston garden was a dumb, but the visitor locker rooms were apparently disgusting. Mouse and rat traps, filthy and cold. But as the legend goes Boston Garden staff would aways sabotage the hot-water tank so visiting teams had to either have a cold shower or leave the stadium gross and sweaty. And in the middle of a Boston winter that is bad.

Also, in sports like NFL football or European Soccer/football teams usually travel for an away game. Then come straight back home. The follow week they will host.

in sports like Baseball, Hockey and Basketball teams usually go on road-tips where they play at several away stadiums in a row traveling from city to city. Sometimes playing back to back nights. Sometimes a team will have a game that will end at 10pm and they will be going straight to the airport to get the next city.

doing this for days and days on end can be EXHAUSTING when you are playing a rested home team with players that got to sleep in their own bed and eat a home cooked meal.

It’s currently 22 dollars for a pound of chicken where I am. I used to eat a lot of chicken, now I’ve started a garden and grow my own foods. It’s healthier, sure, but this is all a little scary because I’m about maxed out. I already make my own clothes, I make my own paper, hell I even 3D print pieces to things that get broken because it’s cheaper than ordering the parts. If it gets much worse… I have very little wiggle room. :(

There are (roughly speaking) 3 parts of most modern websites:

  • How it looks (trivial to steal)
  • What it does locally (easy to steal)
  • What the server does in the background (very hard to steal)

The first is trivial to steal, there are even browser plugins that let you just download the Websites "look" part (HTML + CSS + images + etc).

You can imagine this like going to a theater play and taking a photo: You get a one time still image of the play, but nothing moves / does anything.

​

The second is a little harder, but still possible: All logic that happens in the browser (like pressing buttons, loading comments, writing a response on reddit) are (partially) managed by Code that is running in your browser. (mostly JavaScript) Since this code needs to run locally, you can just go ahead and save that too, but to make it work again, you might need to so a very minor amount of setup.

In our theater analogy, this is like kidnapping the actors. They will keep doing stuff you tell them to, but the scenery in the background doesn't change. So you cannot go on to the next act of the play, you are stuck in the second act (or whenever you took the picture and the actors)

​

The third part is what is normally referred to as "backend". There is a server somewhere, that talks to a database and gets the data to your browser (like a reddit post for example). This server also gets the good looking part ready for you, as well as the logic / code part, and gives it all to the browser to display and run. You cannot take this code, as it does not run on your computer, and only it's output ever reaches you.

In our theater analogy you can think of this, as the set designers and directors. They work in the background and never appear on stage. And since they never appear on stage, you cannot photograph or kidnap them! But they organize that all actors appear at the correct time, and they paint, build, and display the actual set design. Without this part, any reasonably complex play cannot be copied. And the same goes for websites.

The age is irrelevant - the ULEZ is charged based on the declared Nitrous Oxide emissions from the car. However it's been illegal to sell new cars in the UK that don't comply since about 2005, which is why you often hear the age of the car being brought up - but the age itself isn't actually relevant.
