    Hank didn’t mention this but PLEASE keep an eye on your freckles and moles,
    especially new ones that appear as you age. If they’re suddenly bigger than
    6mm (about the size of a pencil eraser), have an irregular border, change
    color, or have an inconsistent color, get it checked by a doctor as soon as
    you can. I cannot stress this enough, cancer sucks, and while it’s awesome
    that we’ve managed to turn most cancers from a terminal illness into
    chronic illnesses, early intervention is still key. Source: both my dad’s
    parents died from cancer; my grandfather from lung cancer and my
    grandmother from breast cancer.
