If you use a Mac or iPad or iPhone, you may find the following tips to be quite useful. The first link lists 33 of the best tips for the Mac. The second link lists 41 great tips for the iPad and iPhone. One can spend a fair amount of time browsing and trying the various tips.
As one example, I found that outside air quality can be found by opening the 'Weather' app on the iPhone and scrolling to the bottom. I hadn't tried this previously. Unfortunately, the air quality where I live in Scottsdale showed "Very Unhealthy". Yuck! Air quality is an issue we often face in the wintertime due to thermal inversions.
Anyway, I hope you find these tips to be helpful.
