But doesn’t the B bulb literally mean a bulb that you’d use as a shutter release?

No. Here is my old Zeiss Icarex S TM Pro. It has two flash connections- one a lightning bolt (flash) the other a bulb (for flash bulbs). Maybe they did not use "B". Some cameras (like old Hasselblads) used an "M". Bulbs burned with different timing than flash, and needed different shutter control. The Zeiss has a focal plane shutter, but leaf shutter cameras did something similar.

In the N.Y. Times crossword today was the clue (3 down) “Early means of providing light for a photograph.”

Lightning?

Interestingly, my Mamiya TLR lenses (the newer black ones) still had "M" or "X" on them. I think even in the late 70s/early 80s they may have still used flash bulbs for some special purpose work (say lighting huge interiors).

There is a "B" as an indefinite shutter speed (i.e., as you may be implying, hold shutter open-typically with shutter release, count, then close by releasing).

Gary makes his own bread.

He'd likely back off on that if he were trying to cut calories. Flour is astonishingly high in calories - makes it really hard on bread-lovers like me! I like to bake, period - breads, muffins, pie - and I like to make my own pasta, too. It's fun and yummy, but cruelly high in calories. You can allow yourself most anything, of course, as long as you pay attention to portions and splurge only occasionally.

Here, kitty, kitty. Hmm a cat that can run 40 mph, take down prey of up to a 100 lbs, and jump 10' straight up, is loose in the Birmingham suburb of Pelham, police advise not to approach -- No kidding. 'Please do not shoot:' Domesticated African Serval 'Juno' lost in Pelham, wanted by owner

I think I'd leave that cat ALONE!
Had leftovers for dinner. Some of the last two nights.

And that's all the news that's fit to print.

That looks like something my cat would do.

Gary tends to think of carbs as pure sugar ... and 'sometimes' limits his consumption of breads based upon that fearful assumption. (For the record, carbs are a combo of fiber and sugars.)

In the N.Y. Times crossword today was the clue (3 down) “Early means of providing light for a photograph.” The answer was “flashlamp.” I’d never seen that word before. Were there flash lamps? Sounds like an oxymoron to me.

Flashlamps uses “Flash Powder” which is ignited remotely to create a flash of light for the photograph. Gary doesn’t think they were very safe. Previously, the flash powder had to be ignited by hand ... so an electrically operated/ignited flash powder was a significantly safer methodology for creating a flash of bright light.

Gary thinks the shutter in those days of flash powder was manually operated (not mechanical). The photographer removed the lens caps and went “one-Mississippi, two-Mississippi, three-Mississippi ...” until a proper exposure was attained, then slapped the lens cap back on the lens.

Mary Lou and Gary spent a pleasant afternoon watching Infinity Wars. 2.5 hours of movie, nearly all entertaining, (if you’re not a big Sci-Fi/Marvel fan), or completely entertaining (if you are a Sci-Fi/Marvel fan).

Sugar (sucrose) is [effectively] half carbs and half fat (fructose is metabolized by the liver into fat, much like alcohol).

Actually, they are both carbohydrates. Sucrose is a combo of two simple sugars, glucose and fructose. Oddly, both glucose and fructose share identical chemical formula but their molecular structures are different.

Glucose is the sugar of preference by it body. Glucose generates insulin to be released into the bloodstream which facilitates glucose to be absorbed and metabolized immediately by the cells or stored as glycogen. Fructose does not generate insulin release and is largely only metabolized in the liver, as you mentioned. Fructose gets metabolized after sucrose and tends to be stored as fat (lipogenic), as opposed to glycogen. The body breaks sucrose into its basic two sugar components of glucose and fructose, then treats the sugars separately as described above.

Table sugar is a sucrose.

I think we agree. I said "Sugar (sucrose) is [effectively] half carbs and half fat..." (1/2 glucose = food; 1/2 fructose = toxin processed into fat by liver).
