Lol Bayya, kai da kasa 'some dreams do come true', ought to of all ppl understand what that quote meant.
It is easier to build strong children because all u do is give them good nourishing food a sound education and good upbringing to make them strong. Bugu da kari, they are on the verge of starting life and hopefully have no horrendous experiences, if they are well looked after.
A broken man/woman on the other hand is someone who has had some devastating experience(s) that have somehow changed him/her in a negative way. They find life not worth the effort or worth living. They are full of regrets of how life has turned out and there is probably no second chance as time is against them. They are not starting out in life as is the case with children. They have already had a great share of life and it probably hasnt been pretty. Also one cant break them of some of their bad habits as they are set in their ways.
PS too many psychological problems attached to broken ppl.
