I obviously passed selection and had to endure 3 years rigorous imbibment trying to drain the KK lake.
I had one problem that I never managed to resolve in 3 years. I used to get heartburn drinking Keo. The solution was to switch from one Keo product to the other. In 3 years I never figured out whether it was the brandy or the beer that was the problem.
Anyway, whenever I switched the pain went away only to be replaced some hours later with a different sort of pain else where.
Now the beer that reaches parts that other beers don't reach was dead easy to diagnose. Absolute paralysism was the clue.
