At 20 - A man is like a coconut, so much to offer, so little to give.
At 30 - He is like a durian, dangerous but delicious.
At 40 - He is like a watermelon, big, round and juicy.
At 50 - He is like a mandarin orange, the season comes once a year.
At 60 - He is just like a raisin, dried out, wrinkles and cheap.
