Just to step back a minute to the original post, I work in Calgary at about 3400 ftASL but I live in Bellingham close to sea level. My blood pressure is consistently higher in Calgary than in Bellingham, mostly the diastolic, year-round.
It could be
a) the altitude difference,
b) the low humidity vs the higher humidity,
c) the stress associated with working vs living at home,
d) what I eat in the two places.
I might point out that I have learned to not accept stress in my life. Years ago I had a staff job with high stress. I learned anger management and that helped me enormously. Then I got laid off and my blood pressure dropped way down. Now a contractor, I do not let stuff bother me. If everything goes to hell, I know I can retire in Mexico.

I am retired.
And I don't care how big your truck is."
