Damn, Lynn, you were breathing old, dirty dust from the digging and vacuuming time too. Using a shop vac doesn't trap the fine particles, unless it has a HEPA filter bag in it. I started using one in my shop vac and noticed a big difference in air quality right away.
You be careful...
I hear ya on the heat. We had, yet again, the hottest summer on record with the most days at 100 ever too. We are NOT accustomed to that up here and we get humidity too, which makes getting anything done outside almost unbearable.
