Thinking gives me a high very similar to runner’s high. I am extremely familiar with runner’s high but as I have gotten older and live in areas that are not as accommodating to extreme sport, I have traded the body high for the brain high.
I am contemplating what I just did with the past 2 or 3 hours of my time. I have just been following my thoughts where ever they take me. My thoughts might seem random until I find that thread. I was exploring the cost of living, gaming, modding computers, and my latest obsession, sound.
Now I am ready to “focus”. I always warmed up when I exercised. I guess that I warm up when I think.
