I think one of the most amazing side effects of studying history is the gratitude that it generates. If you really study it, not just memorize facts and dates, but really put yourself into the time period, in the shoes of those who were there, you marvel at all that they went through. You marvel at how hard it was to get something to eat and to prepare it for your families. You become grateful for the fact you can just turn your faucet knobs on your tub and get lots of water just the temperature you want, and that you can enjoy this luxury every day. You become amazed that you do not fear that the birth of a child might take a loved one from you or that at any time you might lose your whole family from a sudden disease. You become grateful for all the heroes who have made this possible.
