Being tall means I won't live a long life?

I'm 17 and exercise all the time and eat right. I'm 6'3. I read being taller means you have a lower life expectancy and that being a guy contributes. If I exercise throughout my entire life, always eat right, take vitamins and stay away from all vices (alcohol, and drugs and such other than coffee, I like it and believe me it doesn't stunt your growth.) could I live into my 90's presuming I won't die of a physical accident?
