Answer:
Long and thin red within with a nail at the end.
I've been argued on my color. Without me you'll die. So many attempts on your life use me so make sure you have many of my White friends.
My flavors ranges from strawberry to toe.
Glittering points that downward thrust. Sparkling spears that never rust.
I drift forever with the current and flows to your everyday life. I make living easy but I am good at killing people too.
When I'm born I fly. When I'm alive I lay. When I'm dead I run.
