Connection
Not a fitness metric in the usual sense — but the research linking isolation to mortality risk is as real as anything else on this site.
Scoring for this category is still being researched — your inputs below are saved and ready for when it ships.
A directional, educational estimate built on published research — not a clinical measurement or a diagnosis.
Inputs
Two quick, honest answers — there’s real mortality data behind this category, same as the physical ones.
The research
A landmark meta-analysis covering more than 308,000 people found that people with strong social relationships had a 50% greater likelihood of survival than those with weak or insufficient ones — an effect comparable to quitting smoking, and larger than well-known risk factors like obesity or physical inactivity. A follow-up review found social isolation, loneliness, and living alone each independently raised mortality risk by roughly a quarter to a third.
What moves it
- Consistency beats intensity — regular contact with a few people outperforms occasional large gatherings.
- Quality of relationships matters as much as quantity of contacts.
- Shared activity (a class, a practice, a regular group) builds connection as a byproduct, not a forced goal.
Solutions, scaled to you
A low score is never a dead end — it just changes where you start. Pick whichever matches what’s actually available to you right now.
On your own
- Schedule one recurring check-in with someone you already know — a weekly call beats an unscheduled hope.
- Join something with a fixed meeting time (a class, a league, a group) so showing up doesn't rely on motivation.
