When the first computer mouse was developed in 1964 by Douglas Englebart, it was essentially a block of wood with a button on top. The digital age brought the ability to work faster and more efficiently, but the price is often tendonitis, carpal tunnel syndrome and a host of other physical complaints associated with long-term use of the keyboard and mouse. Whether you’re just starting out on the computer or you’re hoping to avert any further damage to your health, an ergonomic mouse can make life at your desk a little easier.
