Anecdotal story: A long, long time ago when Grand Theft Auto 3 was new, I played a 9 hour session without distractions. Immediately after this over indulgence was completed, my mind was completely optimized for real-world fastest path object retrievals. I had to do grocery shopping. No steps in my path were wasted. Nothing but the items I wanted to buy were even seen to me. In what usually takes 30-40 minutes, I completed in 17, with nothing forgotten.
