why do guys always ge so addicted to collectible toys?

To collecting toys is his hobby , i do not think it is bad , but if he spend much money on it , you should think about !

Not just collectible toys - toys in general. It's because men are just little boys in a grown up body. They never really do grow up. They can be amused by the simplest things. It's actually not a bad way to be. Sometimes I envy that trait in guys

I guess its just along an interest of his. Its not easy to change something in a split decisions. An interest in a hobby slowly develops as well as it ends. Indeed, they are expensive, which makes collecting more challenging for some collectors out there. Also with supply and demand, an item would be probably be cheaper if its supply is abundant and it will obviously be expensive when it comes in limited counts, making it a collector's item. As long as he could keep up the hobby, he'll continue on if he wants to or, another reason comes up and convinces him to stop. Toy collections is not only associated with guys, some girls are even more detailed when it comes to collecting toys. But, your point is indeed valid, why spend so much on something while it could've been more better to purchase things that would really matter? Hobies are always a luxury, who knows, if he's ready to let go of his collectioon, it might fetch quite a price later on. Such interests like that can also be considered an investment.
