I wont quote the 5% number, but I have changed multiple ways of doing things in my (daily!) life from tiktok: how i tie my shoes and a bunch of other knots, how I prepare some of my daily food like eggs and potatoes has changed, how I interact with my phone (unknown shortcuts and features). I literally can't enumerate all the things I have learned and used. Two weeks ago, I had to pull a t-post out of the ground and I used a technique I saw a week or two earlier and it made it so damn easy.
