Sounds like you're describing myself! Including the part about meditation. I don't seem to make time for that these days, though that might be changing... (reading The Power of Full Engagement has helped give me a reason to value mental breaks throughout the day) I don't see this as having anything to do with the neurobiology of reward, myself. It just seems like the way my brain works, to be immersed in one thing at a time.

May you rest in peace.

Chris, I admire your graceful diplomacy. You accept the other's forceful energy, while staying on your center and maintaining a strong expression of your own energy back to the other person. It is like watching a good martial artist practice Aikido. :) Also, I share your appreciation for the kinds of play experiences that can be drowned out by more intense elements. Maybe a useful way to explain the difference to those who are unfamiliar could be McLuhan's concepts of "hot" and "cold" media, or in general, of over-stimulated (hyper-sensitive) and under-stimulated personalities.
