I mainly do food tastings, package openings, and cat videos.
I do food tastings mainly for my family and friends. I try it so they don't have to. Hopefully, I can save them from wasting money or turn them on to some great stuff.
I record the opening of packages. To share gifts I receive from friends and family. Also, packages from companies to use as video evidence if there is a problem (damage, wrong item, etc).
And who doesn't love cat videos.
