While waiting for the hot next startup to enable us to defeat disease and live forever, we can make choices today that increase lifespan.
Health is a notoriously contentious field, crowded with pseudoscience: the Sugar Conspiracy and Salt Disinformation Campaign, research burdened by compromised incentives.

Blood donation "donating blood once a year is almost certainly worth it if you're a man" (also contended in comments).

2. Pay attention when in your car.
3. CONSTANT VIGILANCE when dealing with the medical profession and drugs.
4. Exercise: very high return on first few units of effort, some cardio and some resistance training is best.
5. Blood donation every 12-24 months for men.
6. Buy a blood pressure monitor and do blood pressure reduction interventions if needed.
7. Eat fish, nuts, eggs, fruit, dark chocolate. Supplement Vitamin D3.
8. Work towards a healthy weight.
9. If you are losing sleep/are stressed, try one small intervention at a time, and don’t get discouraged. These interventions are the hardest but potentially the most rewarding. Supplements for stress, anxiety, and sleep are somewhat subjective and vary more in reported efficacy than others; self-experimentation is recommended.
10. Floss (and see a dentist).
