I have heard and seen people doing predictions specially health related after seeing the handwriting. For Example the rounds in one's written words i.e. o's, Q's, d's etc are not completed fully or are half drawn consistently then a person can have severe heart problems.
As for identifying Gender by writing, no clue - there might be some study on it for sure but does Amit has that art of identification 😛 BS 😛 😆 😕 he is atrangi, capable of anything u never know.
On a funny note - observe that Girls writing is more curvy and fancy as compared to boys. 😆 😆
hahah loll Anshu you've said something that we could ever think of... hatts to you😉 and I know one thing about hand-writing: if your lines are straight while writing then you have a balanced mind else otherwise - you know what I mean 😆 yes Amit 😆.... girls' handwriting is so decorative & stylish - we never forget to impress examiner with our hand-writing - as first impression is always the last impression😳
