We think we believe what we know, but we only truly believe what we feel.
Deep Survival
Laurence Gonzales
Some simply become “senescent”—useless, but alive enough that they aren’t scooped up and removed as dead. They serve no other purpose except to cause trouble, a little like the zombies of The Walking Dead. And over time, they accumulate. Unlike cells that kill themselves, senescent cells can lead to cancer, which is one theory that explains why cancer increases with age. And if they don’t cause cancer, then their misfiring DNA can produce proteins and enzymes the body doesn’t need or want: loose cannons that begin ransacking the body’s good cells, burdening an already battered body as it ages. In the end, hearing and eyes falter, major organs—including the brain—fail, strength diminishes, the heart stops, and we die.

PROSPECT THEORY
We hate losing money about twice as much as we like gaining it. Losing $10 upsets us roughly as much as gaining $20 pleases us. This bias favoring loss aversion over potential gain is the basis for much of our decision-making.
