I'm in a similar situation, but temporarily sidelined caring for my folks (dementia). I recently had a boss who's been managing tech since '63. He started at 5am and finished around 7PM, every day.

test G counters with a mantle for a gas lantern, like Colman. it's a strong short range source, so when you hold it an inch or 2 away, it'll be loud. anything thats that loud, worry about. less than that, don't worry about. That's what I learned in a Nuke Med R&D/mfg facility.
