ELI5: Why is thirst/dehydration easier to ignore than hunger?
gpt
Only at first....all things being equal and starting at once, eventually hunger subsides in advanced malnutrition. Starvation can take weeks. 

Dehydration doesn't start with a bang like hunger..but it creeps up slowly and hits harder. First, you are just thirsty. Then, *really* thirsty. And it gets desperate. Your head begins to ache, your heart begins to palpatate, you may get nausea or diarrhea (which makes things worse, faster). Then your cognitive abilities slip. The headache becomes agonizing. Your pee goes from normal to orange to brown, then stops. Your kidneys begin to hurt. Your mouth goes dry, your tounge swells..it all becomes agonizing. Really, a horrible way to die. And all that ONLY takes 48 hours. Sometimes less in the right conditions.
