That's interesting. Like you i never seem to get sick, except for the asthma which i think is a sensitivity issue more than much else. Allergy tests from age 8?? to about 26?? always said i was allergic to heaps of things. And they changed. Cotton to wool, vice versa. Always tested positive to stuff until one day i thought stuff it all and just tossed all antihistamines and stopped taking the damn tests. Felt better after that.
With the new for me Trelegy and different breathing exercises i've worked to do myself -- double counts out to whatever feels best at the time in, either 2-3-4 in and 2x out. Instead of the 5 counts in and 5 out i was doing before. Breathing is much better now.
The good immune system working against you i didn't know about. i see now rheumatoid arthritis is one of the autoimmune diseases one could be prone to. Am pretty sure mine is osteo .. and the gout too .. https://www.cdc.gov/arthritis/basics/types.html .
Your desert situation surely has to be healthy for you. At least barring accident hopefully we should have plenty more years to knock about.
