It's amazing how many coincidences happen in daily life. I was just sitting in the park reading in my new book about neurons. A guy cycled by with his bike slowly quietly saying something I interpreted as Graz. As a matter of fact, I was sitting in the town Graz, but why did he tell me this. So I repeated in a questioning voice: Graz? He turned around and said: "grass, weeds..."
Now it got clear to me, he was selling drugs there. I just shook my head and he went off. I thought that I should have given him a stupid answer like "I'm satisfied with how the neurotransmitters in my brain work" because that is what I was just reading about - neurotransmitters.
I read on in my book. And the second next sentence I was reading was:
Many drugs work by affecting the rate and quantity of particular neurotransmitters released and the speed at which they are broken down and reabsorbed.I was thinking: what kind of coincidence was that? Why did this guy have to cycle by at exactly this moment. It really gave me a big smile. So you could say, my mood was elevated by drugs - but as you see you don't have to smoke weed to make yourself happy :)
