Why Westchester Residents Are Upgrading Their Labs

Many individuals in California are turning to preventative testing for three main reasons:

  1. Find Answers Standard bloodwork can miss issues like thyroid, hormone, or autoimmune problems.
  2. Longevity Optimization: You cannot optimize what you do not measure. Function tracks APOB, Insulin, and Cortisol to measure aging.
  3. Family History: Early detection of cancer signals or heart disease risk factors is possible.

Westchester cultivates a strong sense of community, with local parks, beaches, and institutions like LMU fostering a vibrant “right tribe” environment. This natural inclination towards social connection, coupled with ample opportunities for outdoor activity and “move naturally” principles, provides a robust foundation for residents’ well-being and longevity.

However, navigating the fast pace of Los Angeles life and its car-centric nature presents a challenge to consistent “down shift” and “plant slant” eating. While healthy options are plentiful, residents must intentionally prioritize stress management, mindful eating, and integrated daily movement to fully harness Blue Zone benefits amidst urban demands.
