Big companies, especially the Web giants, have made taking care of their best geeks a major part of what they offer, with improved meals, wellness centers, massages and all matter of ergonomics. But not everyone works at these big companies, locked away in bland cubicles or fluorescent-lit dungeons. In the absence of someone else taking care of you, you need to do it. For years, I've put up with people asking 'how I hurt my wrists' or if I have carpal tunnel, and the answer is that I don't, and I'd bet a major reason I don't is because I made sure early to avoid it. As your doctor will tell you, preventative care is the best kind there is, so don't forget to take care of yourself. I just bought a new pair of wrist supports today.
