Lucas Aoun is a Biohacker, Naturopath, You-Tuber and world-class Feather-Ruffler. This time we chat about responsible self-experimentation, the value of tracking choices, actions and outcomes (especially with health goals), our propensity to keep doing what doesn't work, the truth about artificial sweeteners, eating for performance (over pleasure), the pros and cons of coffee, nootropics and psychobiotics (for improving cognitive performance), the beauty and terror of Al and lots more. Enjoy.
