I wear a mask while in the office, and remove when leaving the office to deliver curbside and CBU. I get a new mask daily, and it has trained me to keep hands away from face, and to wash frequently and use sanitizer in between. I'm conscious of what I touch.
Off work, I wear a mask when entering a public place. I don't mask when taking my daily hour or so walks, because I can easily distance from anyone in the park without issue. I shop as infrequently as possible, don't entertain visitors.
I'm not certain where science is on this, as there have been so many reports on both sides. But masks, hands away from face, limiting contact gives us old farts a better chance of not contracting i believe. It's not an intrusion in my life, except the limitations on traveling to see relatives.
The key isn't really the mask, it's distancing and surfaces and not touching face. The mask helps with that, and may also help with contagiousness.
