All of them... and I'm not completely immune myself.
My family just returned from their annual Disneyland Dance Competition trip. In almost every photo they sent me one of them, or more, can be seen on their phone... texting.
When I was in Japan some year's ago... and this was before 'texting' really took off here in the USA... I am not exaggerating when I say nearly every person I saw... on trains, walking on sidewalks, shopping, dining, whatever... was on their phone texting. Only very elderly grandma's seemed immune.
Recently I was watching my granddaughter texting on her phone.... the speed she was 'two finger' typing was incredible. So I challenged her to a race. She's 12. She was approx. 5 times faster than me and WAY more accurate. Then she said something that blew my mind. She said she doesn't have to look at her iPhone keyboard when typing.... I replied, "NO WAY can you do that"
So yes, I tested her. I made her look into my eyes and then I'd give her a sentence to type, a HARD sentence... like, "Witches can't exercise when picking tulips in Holland".
She did it, and did it AT SPEED. Thats' when I knew.. not that I didn't already, but this was final confirmation... the world has left me in the dust. - JamesJM
