In a letter to the French physicist Jean-Baptiste Le Roy sent in the late 18th century, Benjamin Franklin famously coined the phrase that “nothing can be said to be certain, except death and taxes.”

For starters, eating food gets exponentially more difficult with each tooth you lose. Plus, as your pearly whites begin to wilt and drop out of your mouth, you may be passed over for promotions for less-qualified, but nonetheless more toothsome candidates. Pun intended.
