While the website seems very fluff, the concept of hand health can't be overstressed.
Keep care of your hands and wrists. If you feel pain or discomfort, stiffness etc figure out why and fix it. Whether it's keyboard/desk etc change. Or taking breaks and stretching.
Those suffering later stages of hand/wrist strain or wear... look into: wrist straps, wax baths, heated 'wax gloves'
