Is it normal i think i am going to die young?

If you have good intuition, you're probably right. I suggest blowing any savings you have and live life on the edge. If you're wrong, it's only 50-60 years to spend waiting to die.

I fear death all the same. I'm 67 now but still feel as young.

Being raised under the threat of nuclear annihilation, we were sure we wouldn't live beyond today, most days, and 20 in general.
One day on a rare visit to my best friend (from our school days), sharing a particularly nice bit of Northern Californian herb, we looked at each other and simultaneously stated, "You got old!" How the fuck did that happen?"
With good reason our motto was live for today, and almost a whole generation some how did survive to grow old.
You will too, so don't stop living in preparation for dying.
