If you’re a true Jason Bourne fan then you’ve read (and liked) the original books by Robert Ludlum (Books 1-3 in the series).
In the books Bourne (or Ludlum? I’m not sure if I should reference character our author) refers to ‘sleep as a weapon.’
He references, multiple times, that despite being in some terrible situation that taking the time to rest when he can will serve as a massive advantage. It will allow him to make better decisions under stress. It will allow him to survive.
Remember – Sleep is a weapon.
