Much longer than yours so don't worry Around 9 billion years remain. When it becomes a red giant the earth will likely be destroyed as will Mercury and venus etc
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
The sun is expected to have a lifetime of about 10 billion years. This estimate is based on the sun's current rate of nuclear fusion reactions in its core, which will eventually deplete its hydrogen fuel and cause it to evolve into a red giant.
The sun is estimated to have a total lifetime of about 10 billion years. It is currently in its middle age, about 4.6 billion years old, and is expected to remain stable for another 5 billion years before entering its next phase.
The sun is not expected to "blow up." It will gradually expand into a red giant in about 5 billion years, engulfing the inner planets including Earth, before eventually shedding its outer layers and becoming a white dwarf.
The sun's energy is nonrenewable. Because if it explodes it can not be replaced in a human's lifetime (about 80 yrs).

The clock / BIOS battery found in most desktops has an average lifetime of 5 to 7 years. While this is certainly not the expected lifetime of the user, it is about the same as the expected useful lifetime of a desktop.
Many truckcompanies operate with half a million miles as a lifetime goal.
The ozone is expected to deplete more. It is because of the use of CFC's.
A person can be expected to breath in approx. 48 pounds of dust in a lifetime.
It will burn out eventually, but that will be very far from now, not in our lifetime.

The chemicals (usually hydrogen and helium) that fuel the reactions in the star that creates heat and light have a finite lifetime. Our own sun is expected to only last for about another 6,000 years.

Between 2 and 5 years
