"Thank" you. I "will" take a "look" at this bridge.Your own words contradict your statement.
You know less than you think you do; a complicated issue, so you definitely don't have to, or be expected to. But you know a lot less than you think you do.
This isn't the forum for this kind of talk, but.. if you think "you know" security because "your stance" is to "regularly" update your phone?
I've got a bridge to sell you. Nice view too, very scenic.
"Updating" my phone regularly is not why I "think" I know "security."
Do you "know" how much I know?
