In personal ads, do you ever lie about yout stats ? Like Age,hight,wieght. anything else ?

I dont lie i probably should since i have seen that most guys my age look alot older than i do and even most of those my age wont date anyone whos even close to thier age they all seem to want someone younger then them alot younger.some even use pictures that are from 20 years ago. mine are new but i look better in person,digital photos suck .
I probably should lie but i dont. I know alot of people who dont even use pictures of themselves and they will lie about things like how tall they are or thier wieght.
Do you tell the truth or lie online about yourself to make it look like your something your not ? If So why?
is all this internet stuff just a game to you ? do you ever want to acctually meet people through internet dating sites ? if you lie about your stats dont you think they will notice when they meet you? or do you just play with people online who you never intend to ever meet ?
