Firstly, why do you think it's worth it and do you notice a substantial difference in your life when you stop for whatever reason?
Secondly every time I read something like this, or talk to people that meditate, it seems extremely unscientific and filled with subjective analysis. Can you point me to something that would convince me that it has real world benefits, past that of taking a nap, or stopping for 45 minutes to think about your day/life.
