Yes, friends, you can string more than two simple sentences into a compound sentence. (The Chicago Manual of Style says so.) What’s more, they all need to be punctuated as parts of a compound sentence.
“That’s humans for you. Cut off a limb, and it will live, but leave it without oxygen for five minutes, and it’s done for.”
(“That’s lab-grown humans for you. Give it a headache through careful manipulation of atmospheric pressure, and suddenly its ‘superpowers’ are shut down for days.” Hmm… Wasn’t the ‘careful manipulation of atmospheric pressure’ actually supposed to have the opposite effect?)
