How has your life changed since smart phones?

Curious how people who were adults before smart phones were around feel about them now? Most older people I know are just as addicted to their phones as younger adults but seem to be less aware of it (or maybe just don’t care as much) have you personally seen a decline in your mental health (anxiety , depression, attention span , worth ethic , ect) since smart phones have been more popular. I would like to hear how people who grew up pre-technology boom feel about all this considering they got to experience adulthood both ways.
