I know this is not answering the question from the poster but I found meditation very helpful during my recent 15 hours flight. It is very rare to find such a long time alone in an almost quite and non-stimulating environment. Getting meals served to you on your seat and knowing that you are stuck here for next many hours takes away the planning ahead part of the head. I found it easier to be with my breath and thoughts. I also drifted in and out of sleep during this time and felt very relaxed. It helped me upon landing to minimize effects of Jet lag. I believe it was more helpful than any talk or video and could also help getting some good insights.

I'd like to add that my morning 1-2 hour commute is much more enjoyable if I do some exercise before it. If not, I have trouble staying put/sleeping/concentrating on work/meditating, etc. Also, someone recommended to me recently to get a massage before a flight. I'll try that next time.

I found that sports and trivia knowledge is more important than language skills when interacting with the "locals".

What is the source of these numbers? I did not see any age associated with it. I compared my lifts and I was way below the untrained numbers you put up.

What were you expecting to see? Could you explain further?
