Advice for first flight

[mushtafa]

At the ripe age of 39, it's time for my first holiday and first flight!
The first flight is 10 hours, and really don't know what to expect. My main concern is the boredom and my body seizing up!

What tips can anyone give?
I'm going to do some research into noise cancelling headphones, neck pillow to sleep, and change of clothes in my carry-on so I can shower between connecting flights (will have 4 hours to kill).

Can a laptop be taken and used comfortably? Or should I buy a tablet? Is the onboard entertainment usually OK?

I'm probably just massively over-thinking it, but want to make it a good experience.

Thanks everyone, most of it is good advice
I wasn't aware you could just wander about out of your seat.
Flights not booked yet, but the one I'm looking at is Air China which is an Airbus.
Sounds like I need to forget the change of clothes then, and perhaps grab a half decent tablet.

Flight is finally booked. Economy unfortunately! Went for an aisle seat. Now to find some XM4 headphones for sale....
