@pacathy Cathy - I try to avoid being lax, but I have developed my own set of standards that I am pretty strict about. I try to follow Dr Jennifer Honda's advice about picking the few most important protections and "letting the rest go" - so far it seems to work for me.
Here are my big ones:
Good diet of mainly fresh foods, very little processed.
Air purifiers run 24/7/365 and I am fanatical about masking up and changing the filters twice as often as recommended. (We do have visiting furry grand-pets.)
Likewise, the 2 water filters - 1 micron & .2 micron directly under the kitchen tap - are changed often.
I religiously use my Symbicort and other meds, plus a few select supplements.
We buy our 3M KN95 masks in bulk, use them ONCE and discard - in crowds, in doctors' offices, on planes, doing yard work... no sense trying to protect yourself, then carrying germs around in your pocket. These are under 10 cents each on Amazon - be prepared for a BIG box: (https://www.amazon.com/dp/B08J1THV9G)
I rest or sleep when my body tells me to (this is new for me - I always had to do/finish everything.)
Postpone or bow out of activities when I feel rundown or like I may be on the verge of illness.

Like you, I have been exacerbation free all year - doesn't it feel wonderful?

@pacathy So glad things truly have changed for the better for you "This is the first time in 20+ years that I have had a year without a few episode of bronchitis, sinus/ear infections!") Again, how long has it been that you started the BE routine?
In all things there are times when we "fall down" and forget...life happens. Just so long as we do whatever will help correct what we did or did not do in order to help ourselves get back on track or correct. Not easy sometimes.
