You all probably know this but... big stars use fuel faster than
little ones and using our sun as a base you can quickly estimate the
longevity of other stars if you know their mass as a proportion of the
sun's mass. The calculations are findable via google.

I make that a lifetime of roughly over 4,000,000,000,000 years!
getting on for 400 times longer than our sun!

At a professional conference once, I saw an interesting poster paper
(stellar astronomy is my broad area of research interest) about how M
dwarf stars end their lives. My first thought: Gee, what a great paper
to write, since NO ONE can prove you wrong since none have died yet!
