Q&AThe advice to look 20 feet away for 20 seconds every 20 minutes is everywhere. A two-week trial in symptomatic computer users found it cut eye-strain and dry-eye symptoms, but changed no measurable sign of eye health.

Q&AA harmonised meta-analysis of over a million adults found 60 to 75 minutes of daily moderate activity erased the extra death risk tied to sitting more than eight hours. The catch is how much activity that is.
