The sad part is that this guy is already like 76 years old. He’ll probably die of natural causes very soon, that is, unless the Mexicans assassinate him first.
He seems very healthy and vigorous in the video accompanying the posted article here...hopefully he'll honor us all with his fine work for some time yet.
I'm sure that he also has a number of underlings who can step in to keep things going if necessary, as well as to run for Sheriff when the time comes.
