Episode description
This study explores how environmental exposures (exposome) 🌍 and genetics 🧬 contribute to aging ⏳ and mortality ⚰️.
Using UK Biobank data 📊, researchers found that the exposome explains 17% of mortality risk, while genetics accounts for only 2%.
Smoking 🚬, socioeconomic status 💰, and physical activity 🏃♂️ are major environmental influences, whereas genetics plays a stronger role in dementia 🧠 and cancers 🦠.
The findings highlight the need for public health policies 🏥 targeting modifiable lifestyle factors over genetic interventions.
