Keep the brain, mind, and body online long enough to use the life you built.

Cardiorespiratory fitness is the first lever I would fund. VO2 max testing, coaching, zone 2 work, intervals, and repeat measurement beat almost any exotic protocol.

Muscle is glucose storage, fall prevention, medication tolerance, and metabolic reserve. Strength training is not vanity after forty-five.

Tirzepatide has the stronger weight-loss and diabetes-prevention signal, HFpEF outcome data, and a head-to-head CVOT showing noninferiority to dulaglutide with broader metabolic and cardiorenal signals. The neuroprotective story is still early: animal data and GLP-1 class signals, not a proven human brain outcome.

SPRINT is why I do not shrug at elevated systolic pressure in the right patient. The brain, kidney, and vascular system pay the bill.

Statins, ezetimibe, PCSK9 drugs, nutrition, and weight loss are not morally interesting. They lower atherosclerotic risk.

The DPP is why I care about waist, A1c, fasting insulin, triglycerides, and activity before the diagnosis becomes diabetes.

SGLT2 inhibitors are not longevity drugs for everyone. In heart failure, CKD, or diabetes risk patterns, they have real outcome data for heart-failure and kidney protection.

Mediterranean-style eating has outcome data. Enough protein keeps muscle. Enough fiber and plants move cardiometabolic risk. Enough restraint keeps visceral fat from running the meeting.

This is not glamorous. It still beats most expensive biohacks by a mile.

If oxygen drops all night, your morning cortisol and blood pressure are not mysterious.

Sleep is where appetite, insulin sensitivity, testosterone, mood, and blood pressure all negotiate.

Testosterone can matter for libido, muscle, mood, anemia, and function in deficient patients. Menopause hormone therapy can matter for the right symptomatic woman near menopause. I do not sell either as lifespan magic.

Vitamin D, iron/ferritin, B12, magnesium, omega-3, and thyroid status are not sexy. They are cheap compared with trying to outperform a deficiency.

Dexmethylphenidate is not a longevity stimulant. In a properly diagnosed adult with ADHD, it can make the rest of the plan executable. Where dex-specific data is thin, I borrow from the broader methylphenidate-family adult ADHD evidence and stay honest about that.

Colonoscopy, mammography when indicated, cervical screening, skin checks, and lung screening for the right smoking history are boring until they save decades.

A body stuck in threat physiology does not recover well. Mental health is part of longevity, not a separate category.

Hearing, blood pressure, exercise, diabetes, depression, sleep, alcohol, and social isolation all touch dementia risk. Cognitive decline is not just memory. It is losing the ability to manage your own life.

The last five years made sensory loss harder to dismiss. Hearing aids slowed cognitive decline in a high-risk older subgroup, and vision loss keeps showing up in dementia-risk models.

Polypharmacy steals balance, cognition, sleep architecture, libido, and motivation. Sometimes longevity starts by removing what should not be there.

ApoB, Lp(a), A1c, fasting insulin, hs-CRP, ferritin, thyroid, sex hormones, liver markers, kidney markers, VO2 max, DEXA. I like data when it changes decisions.

Low-dose colchicine has coronary-disease outcome data, but the 2024 acute-MI trial was neutral. This belongs in cardiology-level risk selection, not casual biohacking.

CALERIE and DO-HEALTH make aging biology worth watching. Rapamycin, metformin for non-diabetics, NAD boosters, senolytics, sauna, and cold exposure do not beat untreated hypertension.
