Episode notes
Evolution Explains Modern Inflammaging
- Evolution shaped strong inflammatory responses for early-life survival but those same genes harm us later, causing long, slow diseases.
- Modern causes of death (heart attacks, atherosclerosis) begin decades earlier and demand proactive prevention.
Immune System As A Wellness System
- The immune system is a continuous 'wellness system' that links body and brain and keeps us well, not just fights infections.
- Chronic low-grade inflammation from modern stressors accelerates ageing and requires proactive suppression and repair.
Preserve Muscle With Regular Resistance
- Keep using and stimulating muscles throughout life because muscle weakens from disuse, not inevitable ageing.
- Strength and resistance work produce anti-inflammatory myokines and protect immunity as you age.
