@David, Moderator posted:Hi, Ashraful—It depends on the context in which the sentence is uttered or written. If the context makes the point of comparison clear, the second "as"-phrase will be unnecessary. If you do add it in (1), you should change "while" to "about": "If I were half as serious about my life (as I am about playing video games) I'd be a millionaire now." And in (2) it would be good to change "my genetics" to "my genes": "I wish my genes were half as good (as his)."
Thank you very much for the answer and the corrections.
Just an hour ago I was talking about lockdown in Dubai vs India. An Indian guy who currently lives in Dubai said that the lockdown has been lifted due to very low number of cases. I said:
"It makes sense since it's a rich state and not as populated (as India)."
Now I didn't say 'as India' since we were already talking about Dubai vs India. According to your answer I think my sentence was correct. Please correct me if I'm mistaken.
