I am pretty exhausted. Putting my unit together until all hours of the night. Then, taking it apart. Hypoxia drills, hyperoxia drills. So many valves (and trying to remember where they are and how to reach them). Look at the computer. Change the setpoints. Select the gas. Does it ever end?
I brought my Optima home to do some land drills for scenarios. Tomorrow will be two pool sessions.
So far, it is a very humbling experience. It really is as if starting all over again.
