Data story

Your decades, at a glance

The habits that protect your future change with the decade you are in. Move the age slider to see how the body tends to shift and where the leverage is next. These are population trends, not a forecast for you.
45

Your 40s

Prevention becomes the main event.

What tends to change

  • Loss of muscle (sarcopenia) becomes more noticeable without resistance training.
  • Blood pressure and blood sugar problems become more common.
  • Vision (reading distance) and metabolism shift; perimenopause may begin for women.

What matters most next

  • Treat blood pressure and blood sugar seriously; these are proven levers on lifespan.
  • Prioritise strength and protein to hold on to muscle.
  • Have the screening conversations your age and history call for with a doctor.

This is the decade where consistent basics pay the largest dividends.

These are general population trends, not a prediction for any individual. Everyone ages differently. Use them as a prompt for the habits and screening conversations to prioritise, alongside your own doctor.
