I have a friend who's genuinely disinterested in food actually. He likes to say he eats regularly for medical reasons only.
Me too! The only reason I eat is because I have to eat in order to survive. If eating weren't for survival, I would have given up eating years ago.
Some people think sleeping is a waste of time whereas I think eating is a waste of time.
Swedish really needs a "that" for such sentences. The most idiomatic phrasing is Det gör jag också!
Swedish has many verbs that consist of multiple words, where none of them can be left out since that'll changing the meaning completely.
In this case, the verb for liking is tycka om (or tycker om in the present tense). If you remove the om, it turns into a completely different verb.
