What is an Assist?
The Assist is the atomic unit of impact.
as·sist noun
An act of social connection, motivated by fandom and confirmed by the person who received it.
An hour of childcare so she can sleep. A seat at the watch party. A match-day video call. She confirms it. It counts. Teams compete.
The science
Built on six sciences.
MASS™ connects the social science of how teams form and work together with the longevity science of which actions improve health and why. Informed by 96 experts and published for public comment.
