Yes, I learned about tendons when I was younger but it was a word I learned from going to see a Doctor about an accident that happened. I had my left hand injured and I couldn't grip anything for a few weeks. I worked at a grocery store as a bagger while I was in high school.  The cashier put two 2-liter bottles of Pepsi to bag and for some reason one fell on the other and from the pressure one of them came at a bad angle on my left hand. Bagging with only my right hand for about 3-4 weeks wasn't too much fun. Thankfully, I had a really nice Store Manager so he did what he could to give me other tasks that didnt require me to strain my good hand.

This weekend I ended up playing Rayman Raving Rabbids and Cabela's African Safari on the Xbox 360. My right index finger (trigger) and my wrist are so sore. How much is too much when it comes to your hands? I wonder if I'll grow muscles in areas I never knew about in my hands or if I am going to strain them too much and injure my tendons. By the way, Raving Rabbids is so much fun! I am currently having a problem trying to sheer sheep though. Besides the cow basketball (which took me about 30 tries), the sheering sheep is extremely difficult.

P.S. My thumb was doing fine about 2 days after being squished. :)
