Key takeaways
- An annual physical, done well, is the highest-leverage medical habit.
- Blood pressure, cholesterol and glucose belong in every decade.
- Skin, cancer, and eye screenings should scale up in your 40s.
- Family history changes the starting age for almost everything.
The 30s: build the baseline
This is the decade where prevention has the highest lifetime payoff. You feel fine. Nothing hurts. And that's precisely why now is the moment to measure everything — because you'll want to know the trajectory later.
- Blood pressure — annually, more often if borderline
- Lipid panel — every 4–6 years if normal; sooner with family history
- Fasting glucose or HbA1c — every 3 years, or annually if overweight
- Dental cleaning — twice yearly
- Eye exam — every 2 years
- Skin check — annual visual check by a dermatologist if you have sun damage or family history
- Cervical cancer screening — every 3 years (Pap) or 5 years (HPV)
- STI screening — annually or with new partners
The 40s: watch the drift
This is when things quietly start moving. Blood pressure creeps up. Cholesterol shifts. Blood sugar edges upward. Small drifts become important.
Add to the 30s list: mammograms starting at 40 (or 50 in some countries, depending on risk); a baseline colonoscopy at 45 or per local guidelines; a discussion of coronary calcium scoring if you have cardiovascular risk factors; testosterone or perimenopausal hormone conversations when appropriate.
The people who reach 80 healthy usually knew their baseline numbers at 40 and did small course corrections. The ones who arrive at 60 with a crisis often skipped the boring decade in between.
— Dr. Aditya Nair
The 50s: full engagement
Add or intensify: colorectal cancer screening (colonoscopy every 10 years or per current guidelines), bone density scans especially for post-menopausal women, more frequent skin checks, shingles vaccine at 50, hearing tests as a baseline.
This is not "a lot of tests." This is basic maintenance for a body that's been in daily use for 50 years. Cars get more attention than this and cost less to replace.
What to bring to an annual physical
A short list beats a long one.
- A written list of any symptoms, however small
- Your current medications and supplements
- A rough family history (heart disease before 55, cancers before 65)
- Any questions about specific tests
- An openness to boring answers — "your numbers are fine" is the goal

The takeaway
Prevention is the least glamorous, highest-value form of medicine. A yearly physical, the right screenings for your age, and a clear picture of your family history is enough to catch most serious things while they're still cheap and easy to treat.
