Totemo Ii Desu
If it is only this sentence alone…. and correct the only sentence i can think of it “I like myself” Since Japanese language usually opt out watashi and anata in their daily conversation, this is the only translation that come to my mind. Proper Japanese should be watashi wa XXXX ga suki desu. XXXX is the object you are refering. Meaning: I like XXXX.
[the, my, your… depending on who’s body you’re talking about?] body is very good.
As in very healthy, I should think.
“your body is okay”
-I think this expression is used in medical services…
