I am constantly amazed at the ability of a salamander or a starfish to regenerate limbs or other bodily parts lost to predators. Humans have a slight ability to “fix themselves” like when a split heals or a broken bone knits but once a woman loses a finger or an arm as well as a leg, they are gone forever. Some machines have the ability to self-repair… Robotic hands that option fruit or do other tasks that require a soft touch may get “injured” if their jelly-like plastic skin tears during a task. Polymers that form current skin are used to mend the hand without any disassembly or the need to take the area back to a maintenance shop; Even in our homes, some items appear broken but come to life after a while. My laptop crashed the other day as well as no matter what I tried to do; I could not get it to reboot. Then I made a last-ditch effort to get it working by twisting a few wires in the adapter as well as charger that had come loose. It’s not a permanent repair but it is better than having to buy a current laptop, then unluckyly, a home’s Heating, Ventilation, as well as A/C plan has never been known to resurrect itself. The ductwork will not scrub itself as well as the expansion as well as contraction of the joints will eventually result in leaks. The blower fan will not re-align itself as well as an cooling system cannot recharge itself with refrigerant. I guess a self-repairing as well as self-cleaning Heating, Ventilation, as well as A/C plan would be great but for now, the services of a qualified Heating, Ventilation, as well as A/C worker are the next best thing to prevent the loss of a metaphorical “arm as well as a leg” from an costly maintenance or total Heating, Ventilation, as well as A/C plan replacement.
