stuff like that

  1. Our party agenda is: health care, education, welfare and stuff like that.
  2. That is a terrible practice and I won’t practice stuff like that.
  3. He took me to a place where they served meat, egg, beef and stuff like that.
    Please correct all.
    thanks.

‘stuff’ is highly informal. It should be avoided in some contexts.

I think ‘things’ would be harmless.
