Booming sales of laptops have led to a surge in the number of computer users with back and muscle problems, experts have warned.

Girls as young as 12 are being diagnosed with nerve damage caused by slouching over screens, a group of leading chiropractors said.

Millions of others are at risk of “irretrievable damage” to their spines, necks and shoulders because of poor posture when using laptops, it was claimed.

Back specialists say as many as four in five patients have chronic nerve damage caused by working on portable PCs.

As an early (1986) laptop adopter, I can attest to this. Though in some ways using a laptop is better — your posture may be bad, but if you use it in lots of different places it’s at least variably bad. But this stuff is nothing to sneeze at. You’ve been warned before.

Maybe what you need is Yoga for Geeks!
