..The thermostat regulates heat in cars, business buildings, stores, homes, etc. In general, we take the thermostat completely for granted.
.. Modern water purification systems involve a number of inventions: pumps, water pools, circulation system, and most important....filters. The system filters the water and then after filtering, moves it to where it is needed. Now, people take that one for granted too. It is indeed nice to have clean pure water coming out of the faucet...
.. That took a while to achieve. And I am very grateful for those 2 inventions that have allowed human beings to live in a number of places that they could otherwise not live.
