Episode notes
Leadership As Sergeant Major Was Strategic And Hands-On
- As Sergeant Major Billy led strategy while staying operationally involved, stepping in only when necessary to fix critical problems.
- He emphasizes delegation: trust experienced teams, intervene rarely to make high-stakes decisions.
Fit Body Can Hide Falling Testosterone
- High fitness doesn't guarantee optimal hormones; Billy's testosterone sits at 13.6 nmol/L, technically normal but below ideal for younger men.
- Aging lowers testosterone inevitably; symptoms (fatigue, low libido, irritability) determine whether to treat, not number alone.
Use Risk Scores To Prioritise Heart Prevention
- Use a QRISK-style estimate to guide prevention; Billy's 10-year cardiovascular risk is 12% so act now rather than wait.
- Target modifiable factors first: treat high cholesterol and blood pressure to lower long-term cardiac risk.
