Takeaways
- The "Biological Age Test" thing - while crude and oversimplified, does seem pretty complex in how it's calculated. There's been a few iterations now, each improving on the last, and it seems that many variables are considered.
- Biological age tests are based on measuring CpGs - need to learn about what this is.
- Horvath has a theory which is challenging Sinclair's (that of epigenomic decay) and has done studies that show "no evidence of increased epigenetic ageing" when causing random DNA damage.
