Is it possible to have a permanent trip? My significant other and I were driving through the town he lives in and there was a guy riding a bike down the sidewalk. He looked about 60 or 70 years old. My SO says "see that guy right there? He took a hit of acid in the 70's and never came down. All he does all day is collect cans and rides his bike through town. He's only like 45 years old or something." I never knew that was possible! Could it happen?
