I think exercising for half an hour every day is good for your health, if you were a very fat person in college. If you insist on exercising or fitness for half an hour every day, then I can guarantee that even if you are panting at first, you may run as fast as an athlete later.
Not only that, after four years of half an hour's exercise every day, your appearance and temperament will change greatly. I think maybe you want to go home after four years of college, and your relatives, especially people in your village, may think, who is this person? Why don't I know him? Is he from our village? Not only can you scream, you are fat, but you will also make people think that you are a man full of strength and masculinity.
Of course, if you play games for half an hour every day, you may feel nothing at first, but after four years in college, you will find that you are useless except playing games every day, and your eyes are getting closer and closer in the process of playing games. The result is that after four years of college, you have learned nothing. Not only did your graduation thesis fail to meet the requirements, but your relationship with colleagues around you became strange. Even you don't know, is this person your roommate? Are you classmates?
So I think that after four years in college, I can make a careful comparison after exercising for half an hour or playing games for half an hour every day. People who keep exercising for half an hour every day must be very successful in life, while those who play games for half an hour every day, although there is no lack of possibility of success, I think there will be some resistance to their success. One is very successful and the other is very degenerate. I think success or failure depends on your choice.
