Don't go jogging too much when you are young. Don't be like those 蜀山劍俠 uncles loiter around badminton courts. Look lile a bloody fool in sports gear. Your knee caps will burn out first. Old must admit old, dress maturely, and behave maturely. Don't try to look sporty. When you are old, only money can attract young girls. Not your expensive badminton rackets.
