If a person is going into politics because they crave fame and recognition, they're a shitty politician and we shouldn't reward that kinda behavior. They certainly aren't honorable.
The people who should go into politics are people with firm principles who have something they believe in, and are willing to potentially take flack in order to achieve those goals. Unfortunately, that mostly describes the Republican party, and their principles suck, but it also describes Zohran Mamdani who should be the new model of Dem.
I haven't quite hit thirty yet, but my friend has. She's taken up boxing, which might seem counterintuitive, but building up your strength is a great way to avoid having a weak core and knees. It also means she does regular stretching.
