Old men or young men, who is more unreliable?

In Hong Kong TV series, middle-aged women seem to have a catchphrase: men are all unreliable. Men who look honest and simple-minded disappear into the sleazy places when they return to the mainland; before marriage, men in their forties appear steady and capable as if they can help you with everything, but after marriage, it turns out that he needs your care in life like a little brother; one hopes her husband to be a spiritual support when she is already weak enough, only to find that every time there is a small ripple in life, he immediately becomes at a loss and looks as if the sky is falling down, so she has to comfort him instead; she does not expect her husband to achieve great things for her glory, but only seeks a stable life. However, unfortunately, he becomes lazier and lazy, just hoping his wife to earn big money. Originally, she thought she would follow her husband wherever he goes, but now she has to support him instead.
