Hi I am a 27 year old unmarried boy height about 5'3" feet. All my elder and younger brothers are taller than me however my parents are of small height and also my grand parents from both the sides were of medium height. Brothers and cosines of my parents are also of good heights. Some of them are about six feet tall and some are 5'7"-8" could you please advise what went wrong with me what I can see probable reason is that my diet was not good in early days and also the life style that I have had was also not that active for 5-6 years. Could you please suggest me if it possible to and how can I also increase few inches. Thanks in advance.
