At least toady I feel a lto better, can almost type and care to fix my mistakes. :lol:
I have windows open in winter as long as it is warmer outside than inside. As soon as it gets cooler out there than in here, they get closed, so I don't have to pay for heating (as much). Day before yesterday that was from a bit before noon until almost 4pm. Yesterday it was from about 1pm to a bit after 3pm. Also have to close them when people run their fireplaces or are out smoking, or when they have their cars opened up runnign their music at full blast (while they go inside their house and shut all their windows and doors).
But today it has never gotten warmer out there than in here (about 63F in here, and 58F out there), so windows and doors all stay shut except the back door for doggies to go in and out, and it has a big flap as it's bottom 1/3 for them, plus the rooms are all curtained off at doorways with blankets so the heat does't all go away (and the cieling vent in kitchen is sealed since i only have electric cooking stuff, and i try not to burn things :lol

.
Curtains (rather, blankets) on big front room window facing south are open, to let the room heat from solar during the 1230pm-330pm timeframe when sun can shine in. After that I close the curtain in stages as parts of the window are shaded, till around 5pm=ish when more heat leaks out than is put back in and I close them completely, tucking the blanket into the sill space to trap heat inside the room.
(in the summer things are the other way around, opening doors/windows at night after temps outside are cooler than inside, etc).
However, around here, especially in winter, the good air is NOT outside, because people leave their cars running for 10-20 minutes to warm up before they drive off, even in the afternoon.

Totally unnecessary, especially since much of the time they are only gone for that amount of time, probably to grab something at the convenience store half a mile away!
When it's warm enough for them, they stand outside smoking, and for whatever reason it seems like all cigarette smoke comes my way, and gags and chokes me, wherever I am.

Makes my lungs hurt even when the other two don't happen.
Then there are the large number of idiots taht think they must light their fireplace as soon as it drops below 70F outside, so the woodsmoke then does the same thing the cigarette smoke does, only it's denser and present for much longer, often bad enough to keep me from going out for evening or nighttime walks with the dogs even in my own yard, in winter.
So...generally teh air inside is much better than the air outisde. I have hepa filters I can run when I have to, and sometiems one is running along with the box fan when I'm trying to sleep to help drown out the noises of things that wake me up.
Soda pop is a very rare treat, usually only when i am out at lunch or dinner with someone else who's buying in trade for something I fixed up for them, or similar cases.
Coffee = biohazardous toxic waste.
Tea, well, I try to get "decaf" tea when I can find it at dollar stores, whihch is rare. but plain water, especially teh stuff in our city taps, is pretty dismal as a day to day constant drink, so making some form of tea with it is about the only way I will keep hydrated. Green tea is my preference, especially the kinds that are naturally sweeter, but those are hard to find cheap. Although if I could afford it I'd always buy Bigelow's Constant Comment Decaf version, even though i'ts a black tea not a green one, because it has been my favorite smelling/tasting tea since I was a kid, and has always been one of those "special treats" i give myself on rare occasions when it's on a really good sale. (but you only get something like a dozen or two bags for $4-$10 nowadays, and I can buy 80 generic green or black teabags for a $1 that are "good enough" to drink, leaving me with lots more money for food and bills).
I don't do energy drinks. most of them have something in them that makes me really sick, for days. I dunno which ingredient it is, but it nukes my whole digestive tract.
