|so old school|
|cardiology cool. already outdated.|
Soon though, the green laser pointer will also be outdated because now there are PURPLE lasers which became commercially available in 2010. Right now they are a bit expensive, but I imagine that by the time I'll need one they will be more affordable. Or, if anyone was looking for a very very early birthday or Hanukkah gift for me, I would accept a purple laser pointer. Although the one time I taught a lecture as a TA during my undergrad, I was so excited to finally use a laser pointer - but because I was nervous, my hands were shaking slightly uncontrollably, and using the laser pointer made it so obvious that my hands were shaking that I had to stop using it. SHOW NO FEAR. So first, confidence. Then, purple laser pointer.
