Thanks Riley'sLife.
I'll follow

Buy new chair and / or desk for correct positioning

Go to massage every few days

not really things you could not have thought about yourself...

The laptop should almost be at eye level. Good advice above. Buy one of those small USB fans that sit underneath the laptop - that will raise it up a bit.

Yes, its about posture, the lap top being too low and your chair being unsupportive of your lower back. But an easy solution would be to work from your sofa, assuming you have one. I sit on the sofa sometimes and the desk or table other times and that has worked for me, i rarely suffer from back pain anymore. And best of all, i didnt need to spend any money.

As clever as Mr Swiss is, none of these things are necessary. Just be aware of your posture as you work, Make sure it is a good posture for working on a computer, as has been suggested in the thread. Move position often from one good posture position to another relatively frequently- laptops are great for that. Take breaks.
