The majority of my friends have had their boobs done and im one of the few who is super happy with the cards i was dealt. I do see myself in the future after kids which i imagine will be in my mid 30's i will opt for breast augmentation.
However i dont see anything wrong with plastic surgery at any age. If it makes one feel better about themselves then go for it!
On a side note- Im a boobs kinda girl. I'll admitt i check them out.
