# Bortz Age League

Canonical HTML source: https://longevityworldcup.com/league/bortz

Requires an eligible bortz result. Rank by lower bortz age minus chronological age at that result, then earlier date of birth and athlete name.

Field size: 38. Current standings, not a completed-season result.

## Field definitions and dates

- Scores are in years; lower and more negative values rank higher. Sorting uses unrounded scores; tables show two decimals. Rank is within the named view; Ultimate rank is a separate column.
- Age reduction is biological age minus chronological age at the selected test. Crowd age reduction uses the current-image median minus current chronological age.
- Lowest clock ages and their test dates refer to that clock's selected result. Not available means no eligible value was recorded, not zero.
- facts_changed_at_utc records an observed change to this document's facts. Unknown means no historical change date has been verified. Cache refresh and response-generation times are not publication or test dates.
- Competition rules: https://longevityworldcup.com/ruleset. Completed-season results: https://longevityworldcup.com/history.

Score: Bortz age reduction. Showing 38 of 38 athletes.
