Yes. To live forever would violate the laws of thermodynamics. The only way not to would be to have no changes, which would not be living.
death is inevitable
Death is inevitable.
"It was inevitable that that would happen", "his death was inevitable", "losing that match was inevitable"...
birth and death are two inevitable phenomena
believe that they are hastening an inevitable death
You cannot. It is inevitable.
Death, change, and taxes are three things in life that are considered inevitable.
Death and taxes
No one can avoid death as it is man's inevitable fate.
Change is inevitable because without change there is no growth. Without growth, there is stagnation, and ultimately there is death.
This is how I see it: Inevitable = Not Avoidable now or ever. Unavoidable = Not Avoidable now, but is or was avoidable at some point. For example: The saying goes "Death and Taxes are inevitable", (but that's wrong). You are born and one day you die, death is Inevitable. You may try to avoid paying taxes, but it's incredibly difficult, therefore Taxes are Unavoidable, but not quite Inevitable.
Mainly, inevitable death.
