I have been diagnosed with ADD before. Well, I've self-diagnosed myself...
I used to get perfect straight a's, and pay really good attention in class, but it all changed in 5th grade.
When I look back, I realize it was because they took out all the recesses in 5th grade, so we only had lunch hour.
I used to thrive with a lunch hour, and 2 recesses. It was perfect, I would go to class in the morning, then just let loose on the basketball court, and come back to classes drenched in sweat... but all of my energy was gone, and I wasn't fidgety, and could focus in class. Then lunch hour, and another break after that.
Once the recesses were taken away, my grades went down. I just couldn't sit still and focus.
About 3 months ago I decided to bike to work and back, and so I put in about 10 miles a day on my bike. I'm now trying to use my bike to get places. I don't have that job now, but I notice that I crave riding on a bike sometimes. Sometimes I'll be on my bike, and this huge physical energy will overcome me, and I'll just let it drain into my pedaling... I sit and think... wow if I didn't have this outlet, what would happen to that energy?
Just recently, I went to visit my parents for thanksgiving, and didn't have a bike. I noticed 2 nights where my body just felt so uncomfortable... it was like it had too much energy, too much irritability. I tried different things, but it wasn't until I would work out that I could finally feel my body relax.
If I can workout everyday, either biking or just something, my body and mind feels alot better. I don't mind being in a car when I've biked alot that day, or done a lot of physical activity... but when I haven't done much physical stuff, being in a car is hellish. I think its because you just SIT there, and its such a couped up environment, kinda like class.
Just my story. I think ADD is just a way of describing how some people get bored with route tasks. Just becuase one of the posters here takes medication so he can do route tasks on the computer, doesn't mean its right, or good. Who knows the side effects of those medications.
But whatever, people use coffee and caffeine of all sorts (similar effect to ADD meds) to get through their route boring tasks...
