I explored why the habits that extend life—like walking and exercise—often fail to show up in blood test results. Here’s what I found:

• Big Impact, Small Biomarker Change: Walking 12,000 steps daily can add up to 10 years to your life, yet it barely impacts standard blood tests.

• Proven Habits: Combined, regular aerobic exercise, HIIT, and strength training add up to 24 years to your lifespan, despite minimal effect on biomarkers.

• Glucose Reality: Mortality risk stays flat between 75-100 mg/dL, making glucose optimization less meaningful than we think.

The takeaway? Focus on consistent, life-extending habits rather than chasing perfect bloodwork.

Here are two photos of William Shatner. The one on the left is from 1978 when he was 47. The one on the right is from 2011 when he was 80. He looks much younger at 80 than at 47. He does seem to have reduced in age-appearance significantly. I have not been able to find out what his diet consists of or if he takes supplements.
