On my mind..." SKIN"

Her is something that is on my mind.... After all the weight loss since it is rapid(mostly)what happens to your skin? Have you heard this expression... Butt in the front and Boobs in the back? well does it just hang there or does it shrink with exercise? Will I have a stomach that hangs to my knees? The thought bothers me. Hey I lost 120lbs but I'm still caring around all my flabby skin, I can't afford plastic surgery(FOR SURE) but the though of my skin sagging is just as embarrassing as being OBESE. What are your thoughts and what have you done about this or have had too? I know genetics play a roll, but I'm the only Abundant person in my family! So my blogger friends male or female let me know!

Thanks
Laurie
