One thing I know is when you get older your body changes.
I am learning this now as I am getting older. We tend to be more hot or more cold than we were when we were young. And this usually requires more heating, ventilation and A/C. I have noticed that I am more sensitive to the outdoor heat in addition to cold than I was when I was a teenager in addition to young adult. I find myself using the central heating, ventilation and A/C method more in addition to in turn this means higher electric bills. So what I have done to help reduce this is I went out in addition to got myself a portable space heating system for the Winter when I get cold. This way I do not have to turn on the central heating method as much in addition to I can use a lot less energy running the portable space heater. Then in the Summer I do the reverse. Which is I got myself a portable air conditioner. With the portable air conditioning method I can really keep myself nice in addition to cool in the hot afternoons without having to run the central air conditioning truly much. When it gets honestly hot I have to turn on the central a/c for a bit in addition to then go back to the portable air conditioner. But still it saves myself and others on the energy use I was spending by reducing our bills by almost half off what I had been paying. And this is great! Getting outdated is not fun in the least. But I can handle it with our portable Heating, Ventilation, in addition to A/C equipment.
