Going for a Class D License

to become an unarmed security guard (yay!).  It's a 40-hour course that I'm going to take in 4 days. 
Did security before in my 20s, and it's exactly the kind of low-stress (albeit most certainly low-paying = avg. $8 an hour) supplement to my high-stress but higher-paying weekend business...where I can just go, put my time in, sit there, check motorists in, make the rounds on foot or in a patrol car, alert HQ as to any wrongdoings going on, chill out and reflect on life in general and the high-stress weekend experience.  When it's REALLY dead, respond to calls for future high-stress weekend business. 
In the course, I'll learn all the security codes and legalities, basic CPR, how to use a fire extinguisher to put out small blazes etc.  Should be fun.  Wish me luck!
