Answer this question to the best of your ability:
What are some potential limitations of the study on long-term meditation and brain aging?
One potential limitation of the study is that it only looked at a small number of participants, with an average of 20 years of meditation experience. It's unclear whether the findings would be similar for individuals who have practiced for shorter or longer periods of time. Additionally, while the study suggests possible mechanisms for the observed differences in brain aging, more research is needed to definitively establish the causal relationship between long-term meditation and brain health.
