Question: iam 20 now.iam 5.5 in height.if i do stretching exercise up to what height can i grow.any tips plz.? 

Answer: Are you a guy or girl? If girl you are pretty much done growing. If guy you MIGHT grow a little bit more but it won't be much. Most girls reach their full height between the ages of 16-18. Guys reach theirs around the age of 20.
