Jerry, I wish I had your stamina. I barely have enough energy to butter a slice of toast. I think if I had the energy I would make ukuleles for my daughter so she can teach her students music.
What the heck am I complaining about? I’m only 63 and you are an inspiration.

* Argon concentration is much higher than CO2 as it accounts for almost 1% of the atmosphere. Argon must be bad for you since it is an inert gas and doesn't react with anything. It just takes up space that could be used for more productive elements

At least it helps my wire feed make my welds look professional.

As long as you exclude oxygen by flooding your weld location with pure Argon. (Argon+CO2 is used for some welds depending on the material being welded).

And it is possible to make highly unprofessional looking welds with a MIG welder (from personal experience).

I rate a weld successful if it sticks together. The appearance can be adjusted with a grinder and some manual dexterity.

The typical amount of carbon dioxide (CO2) contained in the "fresh" outdoor air is 450 to 500 ppm. NASA gets concerned when the amount of carbon dioxide inside the space shuttle reaches 50,000 ppm.

Please don't waste money on a CO2 measuring device for your home as the indoor air will be near whatever it is outside which you will have little to no control over. Now...CO (carbon monoxide) is far more important because it is a deadly, odorless gas heavier than air.

Very wise my friend

Been there done that.

Carbon Dioxide is not a major concern in one’s household. The major concern is natural gas. It has a distinct odor. This is scented with methyl mercaptan which is harmless but imparts a distinctive “rotten egg” smell.
Similarly, propane gas is also odorized with Ethyl Mercaptan.

One major dangerous gas occurs when mixing Chlorine Bleach and Ammonia. A chemical reaction will occur when the acidic bleach is mixed with the basic ammonia. The result is a very faint greenish gas that is not only suffocating and highly caustic chlorine gas.

When I was a kid we decided to make an element collection. We made Bromine by passing chlorine through Sodium Bromide, then condensing the effluent into a bottle.

We did this in the basement. Without ventilation.

Sometimes I’m amazed that I made it to 15, much less 84.
