There were mysterious questions, but a mysterious answer was a contradiction in terms.

Rationality is the master lifehack which distinguishes which other lifehacks to use.

There are no surprising facts, only models that are surprised by facts; and if a model is surprised by the facts, it is no credit to that model.

Do not flinch from experiences that might destroy your beliefs. The thought you cannot think controls you more than thoughts you speak aloud. Submit yourself to ordeals and test yourself in fire. Relinquish the emotion which rests upon a mistaken belief, and seek to feel fully that emotion which fits the facts.

If cryonics were a scam it would have far better marketing and be far more popular.

Reality has been around since long before you showed up. Don't go calling it nasty names like 'bizarre' or 'incredible'. The universe was propagating complex amplitudes through configuration space for ten billion years before life ever emerged on Earth. Quantum physics is not 'weird'. You are weird.
