If you hope to regain your lost vigor, look no farther. Everything you once had is coming back to you, more than you might actually need. Fire flickers in your smile, even as your eyes send bold, uncoded messages across a crowded room. Telephones ring as you pass, and the call is always for you. Email zips into your inbox as you conduct multiple conversations. You can flirt to your heart`s content and still not commit to anything. And if you were thinking of physical vigor instead of all this other stuff, go to the gym and beat your most recent personal best.
