Do they exist?
I haven’t seen any, but what with numb-skulls walking with what seems to be an extra appendage to their bodies, maybe it is time they had them.
I pass the same woman who walks about 0.5 KM every week day with her phone in her hand swiping with her other hand’s index finger and she barely looks up. I have never made eye contact with her in about 3 years!
I saw one man last week with two phones held up crossing a big road and he didn’t look up once.
Edit:
Today, I saw a guy riding a bicycle holding his phone up level with his eyes, watching a soap opera.
