Exercise will lower blood pressure as well, salt isn't the only cause. You should also look into dropping high sugar products (sodas and sweets) and fatty foods. Drink water! Might help.
I'm not allowed to go outside to play Pokémon go (which make sense. I don't want to look like a dumbass). I can only do it while in the car.
I don't have time to do exercise. I have all honors classes with more than half of the teachers being a turd -.-
