1. Your finger develops a callus from tapping and sliding across the screen.
2. You wake up to go pee in the night and check to see how your game is going.
3. When you've check the game and then spent two hours playing it and other when you should have been sleeping.
4. When your dominate shoulder begins to hurt from repetitive motion.
I'm an addict. I've fallen in love with Fish with Attitude. There are a number of other games I'm addicted to and love and spend waaaaay too much time playing. But Fish with Attitude has caused my iPad shoulder.
In the game you breed fish and place them in tanks. (It's free by the way) They are cute and have personalities. My favorite is the wizard. He turns other fish into frogs for a few seconds. In order to switch tanks there's this lovely feature on the iPad in which you slide your finger across the screen. I have 15 tanks and 3 breeding tanks, plus 25 storage tanks. That's a lot of sliding.
I lost my favorite stylus and so am moving my arm to slide. Over and over and over and over and over. You'd think at my age I'd know better. It goes to show how stupid we can be in our old age. So now my shoulder aches. How'd have thought moving your hand across a screen would do that?
Well, I'm going to go get something to rub on it to help the ache... Then I have to check my fish.
