"Evidence does not support the use of vitamin D supplementation for the prevention of cancer, respiratory infections or rheumatoid arthritis.

The thing that resonated the most with me was the idea that slow processors need to focus on strategic thinking. I am a 60 year old and now retired software developer. I keep myself busy by actively continuing to code every day. I definitely have experienced a slowing of thinking in the last ten years. I have read that this could be because I have more information to sift and sort but being honest with myself, the machinery is not as well tuned as it once was.
I am fine with all this. I love coding and I doubt I will ever stop doing it for pleasure. I have had to become more methodical and intentional with my time on the laptop but reflecting on this piece, being more strategic would be a wise thing for me to contemplate on.
I have had two heat pumps in the last 20(ish) years. The first one worked ok for heating. Warm air I can only describe as tepid blew out of the registers. The second heat pump is amazing. We live in Madison, WI, so very cold. This heat pump blows out air that feels just like the gas furnace air and is able to heat our house down to around 5 degrees Fahrenheit. It consumes quite a bit more energy at that temp and cost wise gas is better.
I would second @quirkot in all of his points. I consider myself a good home re modeler. I have done plumbing, electrical including replacing all the wiring up to the pigtail at the top of the roof. I will not touch HVAC or gas.
