I bet that when the Sun goes red giant it will not harm Earth at all.
As the Sun loses mass the orbit of Earth will slowly spiral further

Cosmos. But the dark huge red Sun will look cool!






The sun will not lose mass initially . Same mass, just .less dense.
A ton of feathers falling on you will kill you just as dead as being hit by
a ton of iron
But it's surface will be closer, so the pull will be greater.
And as it begins to shed the outside layers, that superheated plasma will
cook everything it passes
..
However I'm not worried.
I have months of food in storage
