Similar but Pistachios. The mechanics of opening the shells and eating them allowed me to focus on the college professor's material after an 9-10 hour work shift. If I showed up to class without pistachios or sunflower seeds I was nodding off in class.
When I was younger they gave me Ritalin, mostly to stop me from burning the building down. It worked, because I never burned the school down.. can't say the same for the neighbors shed... plus there was that incident with the bridge, luckily the fire department showed up quickly.
