I disagree.Lesson of the Day: Age may just a number my body knows how large that number is.
I used to do that when I was a teenager and everyone around me told me that it is a sign that I don't sleep enough. I started sleeping 9 hours a day and it didn't happen again.I fell asleep hard during my meditation last night. I wish I slept that good at when I went to bed
Maybe your body needs some more sleep & recovery?
