Stuff only burns for so long. We might learn more about the geometry of space and that there is more out there at greater distances where maybe even other Big bangs are possible but there is a certain maximum amount of time that a star can exist.
Over the time scales of the life of a proton the maximum variability in the amount of time a star can burn is a rounding error against the scale of numbers needed to express the amount of time it takes for hawking radiation to reduce black holes to ultra long wavelengths of infrared radiation.
It’s not body shaming.
Body shaming would be taking shots at somebody for their body not for their unsuitability to do a physically demanding job for which physical fitness is a qualitative impact on performance.
If you’re going to be expected to carry a gun and run you need to be able to run and carry that gun without losing your breath immediately. I’m in pretty good shape but I still don’t think I would qualify to be a soldier if we had standards for soldiers past the first PT.
