My dad is a really heavy smoker, he almost always has been. He goes out for a smoke almost every other hour. My mom got him to stop once, but then we drove cross-country 3 years ago, and he went out for a smoke he said it was "just one, its no big deal" but he has been since, and he is already showing signs of lung cancer. Please help!

I know this sounds ridiculous. i’m 16 years old, and i think i have high blood pressure. only because whenever i just even do the smallest activity like walking up the stairs, i kinda lose my breath. and then when i run i feel like my heart’s going to explode and i can’t breathe. i’ve ran cross country and track for two years already too.. do i have high blood pressure? if so, what can i do?
