I have nice news and bad news for Senior Citizens. The nice news is that noses and ears do not keep growing with age. The bad news is that the cartilage in these body parts will eventually cut down and barring cosmetic surgery, will undergo the inevitable sag, the bane of a youthful appearance. I feel there is another thing that does not stop growing in old people. That is patience, and I feel this is a nice thing; Newborns have zero patience, and it takes about 10 years for it to grow to perhaps one hour before cries are heard; For Millennials, their patience extends to about 30 hours. The patience of Boomers is quite lengthy however the irony is that Boomers have nothing to be impatient about anymore apart from getting their Millennial children out of their house. Seniors are also superb with giving advice beginning with, “Listen to your elders”, however with a new Heating and A/C system, those bits of advice dispensed by old people are quite valid. Old people tell younger folks to “take care of their bodies” and this legitimately applies to taking care of an Heating and A/C system with a official cleaning and maintenance program from a professional Heating and A/C business. My Grandfather urged me to save money and there are superb savings to be realized with newer and more efficient Heating and A/C systems. My wifey failed to heed the advice of her elderly parents who told her to choose her fiance carefully. She ended up with me, however their advice is valid with Heating and A/C in that many decisions are involved love choosing the officially sized unit, hiring the best installer, or opting for a ductless system. These choices will require the patience of a saint to get the best result.
