Such a good idea, maybe if this was implemented with some sort of stamina bar and/or huger and thirst i think it would work well.
That's another common idea that gets shot down fairly frequently. Personally, I think this could (and should) work independently of those features. As it is, This would not be a huge gameplay change, It would just add a small tweak to make things a bit more interesting. Adding proper stamina, Hunger, And thirst is better suited to a script or mod IMO.
In addition, Stamina would be practically useless and just annoying. Imagine having to stop mining every minute or two to recharge your stamina. Weapons already have cooldowns to their swinging, So that makes that part unnecessary. At that point, The only reason to have a stamina bar would be for sprinting, And I don't think that is worth the screen space. I don't think you should be able to sprint infinitely, But I don't think a stamina bar is necessary.
