2) Dear 28-year-old John:
I’m writing you from the future to let you know that you’re going to have deep vein thrombosis in your right leg later this year. Although it could kill you dead as a doornail, it won’t. However, you will have to give yourself dozens of shots in the stomach, haggle with insurance companies, and take powerful anticoagulants for months. Eventually, you will make the decision to get off the blood thinners on your own because your doctor seemed to think there was marginally less chance of his getting sued if he kept you on the drugs all your life. To this day, I have swelling and discoloration on my right leg caused by the damage that was done by the blood clots, although they’ve never returned. Mysteriously, there was never a good explanation given for what happened. Maybe you’re not getting up enough from the computer? Maybe you’re not exercising enough? It’s hard to say. Just do what you can to avoid deep vein thrombosis.
I got this response back:
Dear future John:
First of all, I’d like to thank you for the super specific advice on how to avoid getting blood clots. Oooh, it’s “mysterious”; maybe this will prevent it from happening — that’s much appreciated. Still, I’ll exercise and walk around more to try to avoid deep vein thrombosis.
P.S.: Is there some reason you didn’t send some stock tips in this email? How did I turn out to be such an idiot in the future?
