Thirty-something

hai, see again , after finish for task 1 , we see again for task 2, for task 2 i choosen Thirty-something as my topic .
This phrase, ‘thirty-something’, it came in in the 1980s
referring to people of an unspecified age between 30 and
40. as ussually, like task 1, i still was using same way , cause it was the hardest to me for understood as fast as possible. here, i know, it was different between english language with others country slang. eventhought, it will take some time, it still can be done. for this topic , i got a new word , such as baby boom , it's mean personal moral standards. so , at last, i was hopefully, my effort this time for improve my english will acchive.
