ikämittaaminen

Ikämittaaminen refers to the process of determining a person's age. This can be approached in several ways, broadly categorized as chronological and biological age. Chronological age is the most common and straightforward measure, calculated from the date of birth. It represents the number of years, months, or days that have passed since an individual was born. Official documents like birth certificates are the primary sources for establishing chronological age.

Biological age, in contrast, estimates how "old" an organism is based on its physiological state, which may differ from its chronological age. This assessment often involves examining various biological markers such as cellular health, organ function, and genetic factors. While chronological age is a fixed number, biological age can fluctuate and is influenced by lifestyle, environment, and genetics. Research into biological age aims to understand aging processes more deeply and potentially identify interventions to promote healthier aging. In legal and administrative contexts, chronological age is the standard for determining eligibility for services, responsibilities, and rights.
