Mental Health Improves With Just Twenty Active Minutes Per Week

Nutty.

"Performing as little as twenty minutes of any physical activity, including housework, per week is enough to boost mental health."

Then almost all of us should have boosted mental health already.

Who does not do 20 minutes of housework per WEEK, except for someone comatose, paralyzed, etc.?

Clearly something more is needed for "mental health."
