Build your health strategy for life.

Biological 401K reframes health as biological capital — a framework for long-term planning, risk allocation, and decisions that compound over time.

The Biological 401K framework

Most health strategies optimize the next 30 days. Biological 401K focuses on the next 30 years — applying long-term planning discipline to health decisions. Establish inputs, measure objectively, allocate attention, rebalance on schedule, and stay focused on the horizon.

Long-term plan
Consistency compounds. The plan evolves.
Intrinsic capacity is the functional expression of biological capital — how well you can perform, adapt, and recover over time.
Year 1
Start Years
Inputs
Sleep, training, nutrition, stress, and environment.
Measurement
Objective markers that guide decisions and reduce guesswork.
Allocation
Direct attention toward systems that most influence outcomes.
Rebalancing
Review on a set cadence—adjust the plan as data changes.
Horizon
Healthspan, resilience, and durable performance over decades.

The Biological 401K Equation
A framework you can measure, allocate, and rebalance.
Healthspan ≈ ƒ ( Bbaseline, Rrisk, Ccapacity, Hhabits, Iinterventions )
B
Baseline
Establish your true starting point.
Measure: labs, history, context
Decide: what matters now
Rebalance: update baseline quarterly
R
Risk Allocation
Prioritize the highest-leverage risks.
Measure: cardio, metabolic, neuro
Decide: allocate attention
Rebalance: risk map every 6–12 mo
C
Adaptive Capacity
How well you respond, recover, and adapt.
Measure: HRV, sleep, recovery
Decide: load vs recovery
Rebalance: weekly review
H
Compounding Habits
Small inputs that compound over decades.
Measure: adherence + trends
Decide: simplify the plan
Rebalance: monthly adjustments
I
Interventions
Act only when the data justifies it.
Measure: response to change
Decide: intervene vs wait
Rebalance: de-prescribe when stable
Course
Each pillar becomes a course that teaches the model and the measurement strategy.
Modules
Short, specific units: markers, interpretation, actions, pitfalls, and review cadence.
Decision Framework
Simple rules: if X, then Y — and when to re-test or de-escalate.
