How to avoid jet lag!

Hey Steve, I just landed from Vegas and I'm super jet lagged.

Why is that?

So, the problem is it's not from jet lag from time zone difference. The reason you're feeling jet lagged is because of cabin altitude.

Cabin altitude in an airplane is the altitude that people feel their body feels that they're at flying and cruising the altitude. So, even though you're flying at 41,000 feet, the cabin altitude on an airliner is between 6,500 and 8,000 feet.

That really tires your body out because it's like if you go skiing, you're based at 8,000 feet. It's very difficult for your body to acclimate to that altitude. It's the same thing on an airline.

Okay Steve, so what should I do about this?

Use the answer: go buy a corporate jet. The cabin altitude on a corporate jet is less than half of what an airliner is. So when you fly anywhere on a long distance on a corporate jet, your body is so relaxed and so hydrated, it feels like you never even flew anywhere.

Great Steve, so where can I get a corporate jet?

There's only one place to buy a corporate jet: The Jet Business. Thank you.
