I can’t believe what Tesla accomplished with this car.

Nobody can sell you a longer life. Not a supplement, not an IV drip, not a peptide. No drug or supplement has ever been shown to extend human lifespan.

What we *can* do is prevent the things that take years away. After 30 years in medicine, here’s where I’d start:

1️⃣ **Protect your heart first.** Heart disease is still the #1 killer in the US, with 683,491 deaths in 2024 (CDC). About half of cardiovascular disease is tied to five things we can measure and treat: blood pressure, cholesterol, blood sugar, smoking, and weight (NEJM, 2023). Know your numbers.

2️⃣ **Check your metabolism.** 115 million American adults have prediabetes, and 8 in 10 don’t know it (CDC). Ask for an A1c and fasting glucose. It’s silent, and it’s reversible.

3️⃣ **Keep your muscle.** Grip strength predicts mortality better than blood pressure in large studies (PURE, Lancet 2015), and muscle-strengthening activity is associated with lower all-cause mortality (BJSM 2022). Lift twice a week.

The goal isn’t just more years. It’s more good years.

Save this, and send it to someone you want around for a long time. 💬 Which of the three are you working on? healthspan

Strength is a vital sign.

In large cohorts, lower grip strength and muscle mass are associated with higher all-cause mortality. Strength training is linked to lower risk of death, CVD, cancer, and diabetes, and lowers HbA1c in type 2 diabetes trials.

Mostly observational, but consistent and low-cost: 2 sessions/week, all major muscle groups, progressive load.
