Giving up eating meat. Not sure if it was cause or effect, but I got so much more interested in cooking food properly and looking after myself. Food and cooking became one of my favourite hobbies and 7 years later is still my go-to healthy wind-down activity that helps me relax after a long day at work. Knock-on effects have meant I’m happier and healthier than I ever had been in my life.
Sorry for devil’s advocate here because I agree with you but hypothetically the answer would be verification. ie., Google already has your password, so why would they need to ask you for it when you log in?
