Texas and Georgia have areas where the soil is sulfur free.
The onions grown in those areas are tear free and called "sweet" onions.
Texas Sweet and Vidalia (Georgia) are the trade names. There may be other patches of sulfur free soil around the world where tear free onions can be grown, I don't know.
In the meantime, I love sweet onions!
This. I think sweet onions are a lot less bothersome to the eye and since they look exactly like regular yellow onions (to me), I can only tell by the smell if we've gotten regular onions by accident (they don't make my eyes tear up but do smell a lot more pungent). Taste-wise, DH prefers sweet to regular but he eats them raw. I only eat them cooked and can't taste much of a difference.
RE: Snooze buttons, I always thought the reason was psychological.
As in, 9 minute intervals ensure that (usually) both minute digits differed every time snooze goes off so it's easier to tell whether you've already hit snooze once or twice. With my fuzzy eyesight and lack of brain in the morning, if snooze were 10 minute intervals, I might not fully process what time it actually was... This, um, "reasoning" is also why I never set my alarm to a round time unit, it's always off by a minute or two (7:02 rather than 7:00).
I was a massive Snooze button fiend when I lived alone and would hit the button (or sleep through) for up to an hour every morning. Since I always seemed to snooze during REM sleep, I would have the most annoying dreams about music I couldn't turn off...
