Exploring the Link between Gratitude and Attention
by Gregg Krech
"If the only prayer you say in your entire life is ‘thank you' that would suffice."
- Meister Eckhart
Your eyes are still closed when you hear the beeping of your digital alarm clock go off on the small wooden table next to your bed. Without opening your eyes your arm naturally reaches over to press the black "snooze alarm" button - a motion you repeat just about every morning. But this morning nothing happens. The beeping continues – and is getting a bit irritating. So now you open your eyes and watch your index finger press hard on the correct button. More beeping. You hit another switch which should just turn the alarm off completely. Still more beeping. In a fit of frustration you finally pull out the cord from the electrical outlet. Ahh.... quiet at last. Perhaps it's time for a new clock.

09:24 pm - Does Running Cause Arthritis?
Is it true that running is hard on the knees, hips, and feet? Runners still hear about that supposed connection, and there seems to be a kernel of truth in the supposition. After all, running is the kind of sport which produces 'wear-and-tear' injuries, not traumatic ones, and one key form of arthritis - osteoarthritis - is a wear-and-tear disease, in which the cartilage inside joints is gradually eroded over time. But what does the scientific literature really say? Do the relentless impact forces of running (a force greater than two and one-half times body weight is transmitted through the leg with each footstep, 1700 times per mile) eventually cause the cartilaginous structures in the knees and hips to deteriorate into the inflamed, arthritic state'?
The most comprehensive study concerning running and disability was begun in 1984 at the Stanford Arthritis Center in the US. Initially, 863 people (632 males and 231 females) ranging in age from 50 to 72 took part in the research. 498 individuals were long-distance runners, while 365 subjects did not run at all. The runners averaged about 210 minutes (27 miles) of running per week, had been running for an average of 12 years, and weighed considerably less than their sedentary counterparts ( 147 versus 161 pounds). Some of the runners had logged as many as 17,000 total miles during the 12 years leading up to the study.
