Whatever the case may be, it's so important to listen to our bodies and determine what we need to do to get our energy back to a "normal" for us level. Have you every noticed that it can sometimes jump from person to person? (Not literally) Someone may say... "gee, I sure am tired," and before you know it, you're like man me too! LOL... well, let's do something about it and get to listening to our bodies and making moves to get our energy levels back to where they need to be. Cut out on those king size candy bars... and throw a few chuckles of laughter in the mix of your day. Laughter tends to help me give a swift boost of energy to my system, and it usually makes other people laugh too. (Well, that's if I'm around other people). LOL!!!
