I have gotten fat because of the central air conditioner in my house.
Now, I cannot blame all of it on the central air conditioner, but I know that the trends of laziness that caused me to get fat were started because of the central air conditioner.
Before I installed the central air conditioner in my house, I was outside of all of the time. I worked outside of all of the time because the inside of my house always felt like the furnace. After a few hours of the sun being up, the house was warmer than the outside temperature. I did not have an air conditioner before, so the only relief that I found from the heat was actually just keeping busy outside. However, I wanted a central air conditioner, so I decided to call the HVAC technician and have him install one. Once I had a central air conditioner in my house, I never wanted to leave. Staying inside was much more comfortable than being outside where the temperatures were warm. Now, I still worked for a living, but when I would normally be doing projects outside, I was inside with the central air conditioner. There was not a lot to do inside, so I started spending a lot of time watching television and reading on the internet. Slowly, I started doing less and less outside, and I started gaining weight too. I know that I made the choice not to be productive, but it was so much easier to be productive when I had an air conditioner that gave me the incentive to do nothing.
