I am seventy (70, for some of the illiterate young, some of 'em who can't read words. But can they count to seventy? Only ten digits, plus nose, two ears.) and I suppose that's old. Treat us as individuals. You did say, some. I am seventy can still do a double century on my Serotta touring bike.
I rooted my phone, got rid of bloat, and, among other things, got twice battery life. I discovered not in the carrier's queue for future updates, next one I C S, I flashed a stock rom. Yesterday message popped up saying Software Update. Now I have I C S. Yeah, I'm old. I read sci fi about global hand held communicators. I have linux, Ubuntu and Android, Macs, Windows in my network, yet mow lawn with pushmower, grind my Sidamo beans with manual grinder, and dont use power saws or clippers. Selective use of tech my choice, I only use high tech when really needed. When on a bicycle tour I can access home. And I'm smarter than most of youse folk, maybe. I ask this question (only answer to yourself), how many of you carry two charged spare batteries and a solar power charger and have a rooted phone with almost twice the stated battery life? You dont worry about not having power for your phone?
Wise folk learn from others; it's sometimes called history, ancient and modern.
Smart folk learn from own mistakes; good if doesn't kill ya.
Fools and folk who dont understand "There are 10 kinds of people in the world:
Those who understand binary and those who don't." Well, I am old, 70, but simply means I haven't been kilt by a bear or anything else yet.
