Being "able bodied" is temporary, you will age, you will get injured, you will get sick and you will wish you fought more for the system to protect the vulnerable.
a lot of people lack basic manners and decency and think it makes them cool and edgy.
learn table manners, don’t show up to things empty handed, write cards, talk to your neighbors, hold the door for people, etc.
you don’t even have to be THAT nice just be considerate.
