Most people forget the hardships once they are through with them, but they have at least a few moments of stress.
Varies extremely between areas, varies extremely between countries, universities, depends on your the amount of funding you receive, if your work is theoretical or experimental, if you can do everything on your own or depend on other researchers/groups, if your experiments are very high risk/stakes or not, if you need to compete for time with others to use some cluster/equipment.
I'm not sure I agree that an academic life being stressful is a sign of stupidity. Different projects yield different amounts of pressure.
My PhD was a suffered experience in part because of health problems I faced at the time and having to deal with other groups and need of materials and that kind of shit. For my postdoc I just need to write code so it feels like a breeze.
In general I would say "Do what makes you happy", but if you really want to do science more than anything (as scientists should), I'm not sure happiness has to play a part. I'd seriously doubt scientists were historically happy fellows.
