    You shrink as you age.

    It begins by the age of 30, and gets steeper between 60-70 years. Most people lose 1–3 inches in height over their lifetime. Men can lose up to an inch per decade after 70, and women even faster, especially post-menopause due to bone density loss.

    My PFAS test results:
    + Total PFOA: 1.04 ng/mL
    + PFOS: 0.57 ng/mL
    + PFHxS: 0.29 ng/mL
    + Total PFAS: 1.90 ng/mL

    My PFOA serum levels are in the lowest 25% for US men aged 20-49. My PFOS and PFHxS levels

    4/ PFAS damage doesn't stop with you. It crosses generations.

    It isn’t just dangerous in blood. It builds up in reproductive organs:

    + PFAS levels in semen correlate more strongly with lower (free and total) testosterone than in blood
    + for women trying to conceive, higher PFAS

    PFAS are forever chemicals.
    In cookware, floss, and fast food wrappers.
    They hurt fertility, the brain, and immune system.

    They accumulate and the body can't eliminate them.
    I got my levels tested.

    Here’s what you can do to avoid your exposure. 🧵
