I tried to go to sleep earlier than that, but I was So Energetic that I fell asleep at 2:10 AM last night ( on March 8th 2018 ) - & My Both Knees got warm suddenly - & They Still Are Warm the next morning! 

( I still don't know Why Just Knees - but that's Funny! 😆 )

*Seems that these are the Points where My Energy chose to cumulate & Stay :D

Lol :)
