The Quantified Scientist - Invidious

The Quantified Scientist

Looking for a scientific view on wearables? Look no further! My name is Rob, and I am a scientist who is into all sort of wearables, but wants to make sure they are accurate. On this channel, I test different devices, and see how I can use them to improve my life.

I am life-logging and quantifying everything about my body, mind and surroundings. My measurements take more than 11 hours a week and include a weekly brain MRI, sleep EEG and gut microbiome composition. I am quite possibly doing the ultimate "quantified self". As a scientist, I specialise in biological informatics, which means I write computer programs to analyse data. I now use these skills to learn more about myself and I try to improve my life.
