My take
16 to 21 is the most vulnerable age, where hormones will be raging and there is natural urge in women to find a partner that is trendy and modern.. media, from Instagram to Bollywood,.leave an strong impression in women as to what is trendy
(1/n)..

During that age, H men are in the thick of rat race, or learning business/work from their parents and focus less on self grooming, honing up communication skills
Plus a girl of that age is far more mature than a boy of a similar age, hence same age man appears kiddish
(2/n)

M kids are exposed to world far earlier in life, plus isn't much parental pressure to study, so they get enough time to undrstnd world and spend on self grooming, improving sweet talk, driving bike etc
Girls get attracted this as it matches what they see in media
(3/n)

For a girl in 21 to 25 age group, they want to use their newly found freedom to do something rebellious. M match that
Another set of girls think of themselves as reformers, and believe they can turn any bad man into a good,and these M kids are a perfect project for them
(4/n)

Plus M kids are willing to date girls far down their level in looks, bcoz they know that these are short term projects for them..
Girls are happy that they got a good deal for life...
H men have lots of catch up to do..
(5/5)..
