iStock; Rebecca Zisser/BIAt 30, I reluctantly bought a smartphone once life with my flip phone became too difficult.Now that I text so much and use social-media apps, I have less to talk to friends about in person.Despite the benefits of having a smartphone, I feel more isolated and like I rely on it too much.I held off on getting a smartphone for as long as I could.Having grown up in the age of cellphones, my flip phone felt more than good enough since I could call and text anytime, anywhere.When I used it in public, people would ask if I was "detoxing" or making some sort of political statement by not having a smartphone.
