Over 60s- make phone calls, usually to 1 person at a time (how quaint);Let me clarify then … they’re generally people over about 60, yelling into their ‘phones on speaker; so if you’re anywhere near them, you get to enjoy both sides of the conversation..
People watching a video without headphones are normally under … I’d say about 30-ish. But I see/hear that a lot less frequently than older people sharing their conversations with the world via speakerphone.
30s- nonverbal apps, often to multiple persons at a time.
