Looked up symptoms of heart disease, and the only one i don't have at this time is fainting. Never been unconscious. But yeah, aside from that i've got all of them.
Potentially. I may not even have it, trying not to get worried about something that may not even affect me.
Looking up medical stuff on-line is a sure way to give yourself a heart attack. So it's kinda a self-fulfilling prophecy. I guess. The right term is eluding me.
... I would wait and go see a doctor first before saying it to the world. No self predictions (even with scientific facts backing you up) please, that's never a good thing. :\
