Digital Twins have been revolutionizing industries for decades. In aviation a twin of an aircraft is flown for tens of thousands of hours in simulation before ever taking to the air. In weather science twins or weather models are continually run in fast forward to prepare for things like landfall of a typhoon saving countless lives.

Twins have also been applied to healthcare helping to speed drugs to market in times of need such as during the global pandemic. However these health twins have been localized to cells or tissues and the mechanism of action of a drug on them. Today, we hold the process of exploring the human system and its reaction to more complex interventions like sleep, diet, exercise and pills on the entire body.
