Episode notes
Trainable Photographic Memory
- Train your memory using deliberate, repeated practice and mnemonic techniques like champions do.
- Read resources such as Arnold Schwarzenegger's Total Recall and practise daily to improve recall.
Illness Leaves Detectable Smell Signatures
- Some people detect disease by smell because illnesses produce volatile organic compounds.
- Identifying those chemicals could let machines diagnose conditions like Parkinson's before symptoms appear.
Why Cryonics Breaks Cells
- Freezing humans kills cells because ice expands and ruptures delicate structures.
- Some animals like tardigrades and certain frogs survive freezing by biochemical tricks we don't yet fully replicate in people.
