"My first cousin (Father's sister's daughter) and myself are in love. But, I'm afraid of the claim that ""Marriages happening between first cousin's increases the chances of diseases at birth for the new kid and also reduces the kid's immunity towards other diseases"". What's Quora's opinion on this?"
My family says I’m too young (I'm 21) for a 27 year old girl to be interested in me and that it won't work out. Is my family right?
