If you ever find yourself in Betty’s position (and I sure hope that you don’t), think of the song “Stayin’ Alive” by the Bee Gees. That’s how fast you need to pump, about a hundred beats per minute. No joke. Love it or hate it, ’70s disco can save lives. Ah, hah, hah, hah, stayin’ alive, stayin’ alive. Ah, hah, hah, hah, stayin’ aliiiiiiiive!! The Queen classic “Another One Bites the Dust” also works, tempo-wise. But I can’t recommend that one.
