Student or Learner
Is it the right way to say the following:
I've always been an underweight person.
Is there a better way to express that?
Thanks a lot in advance!
I've always been slim/slender/thin/skinny.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
