I think teens are less happy nowdays, mostly because we spend too much of our time online, especially on social media. Our parents didn’t grow up in digital era and they spent more time outside and had more human interactions, which creates a healthier lifestyle than what we have right now. Now everyone spends majority of their life on their phone, mainly scrolling through social media, which are very addictive and have really bad affects on our mental health. Social media creates competition "who has more likes/followers", creates unrealistic body images or even more harmful things, so clearly teens now, who use those medias all the time, arent as happy as our parents were that age.
