To all the less than the very young, but not ready for the crypt folk: Do you feel less joie de vivre these days? Just plugging away. Merely alive but not being alive? Well, maybe you have a sluggish blood flow. It happens. Look at the very young: they're always in motion. And the very young are usually quite happy. Because movement is about blood flow. And the older we are, the more we are socialized to stay still. So anything that gets the blood flowing will restore your happiness. And especially if it gets blood flowing to your nether parts--that will really restore your joie de vivre and make you glad to be whatever it is you believe you are. So don't neglect the nether regions when you exercise.
It's all about the blood flow. For your exercise regime, you can start either at the top and move down, or vice-versa, whatever your end goals for the night are. When it starts with your top--it's called "facial yoga." When it starts with your nether parts, oh, let's call it "sexual yoga." Either way, you end up woke and in a glad you're alive sort of way.
Let's, for the sake of argument, start with the face. It's so very easy. Pinch: start with the eyebrows, make a pincer of your thumb and index finger, and pinch the eyebrows up, from corner to corner. Have a mantra--I suggest, "Yum." Walk the pincers up and down the eyebrows, humming the "yum" song. Then, place the palms of both hands in the middle of your forehead. Smooth your furrowed brow a few times. Then, take the pincers down to the jawline and do likewise--walk the pincers up and down, to the left and right. Do the same with each earlobe. Then, give yourself a neck massage and wake up the thyroid--its a sexy gland.
Then, its down to your nether parts. Take your nether lips in your pincer fingers and walk the pincers up and down each side. Wait for it. Within seconds, there will be joie de vivre. Do a few sets of Kegels to tone your vaginal muscles. Of course, there is no reason this cannot be a partnered activity, with each person doing this to the other. If you do this with a partner, be receptive to feedback--too firm, firm enough, or extra firm, please.
See--no need for anti-depressants. I guarantee you that no SSRI increases the blood flow. Like Smokey Bear says, "Only you can increase your blood flow." So take matters firmly in your own hands.
