__**Why do smaller stars have longer lives then bigger stars?**__ Bigger stars have more fuel to burn up, but their rate of fuel consumption is much faster than smaller stars. Smaller stars have less fuel, but the rate of burning that fuel ism uch slower and less rapid then the bigger stars. So, in the end, the smaller star lives longer than the bigger star because the don't burn the fuel they have as fast as the bigger stas do.

__**How long does a medium star live in the main sequence?**__ Medium stars don't burm up their fuel too fast, but they aslo don't save it. This means that they can't last as long as tiny stars such as red dwarfs do, but can still last up to 10 billion years. The smallest of the red dwarf stars can last into a trillion years, and the biggest red giant stars can die young at only one million to fifty million years.

__**After a star enters "old age" how long will it live?**__ After a star has burned off most its gases, and turned into a red giant, or for bigger stars, and red supergiant, it doesn't have much longer to live. 10-25 million years is about how much longer the star will last until it either peacefully burns off the rest off its gases and turns into a neautron star or a white dwart star which will slowly become a black dwarf star, or turns into a magnifisent supernova and into a blackhole.
