I'm 26 and owe about 20k roughly, although I have 10k in premium bonds which can be returned to me at any time so depends how you look at it, I could withdraw that 10k and reduce my debt by half, or leave it where it is on the off chance I win a bit of cash, also have a bit of equity in the house so that reduce's my debt a bit.
Have always been in debt since about 18, started work at 17 on £60 a week, managed to save most of that by spending fook all, living at home and not having a car etc, as soon as the wages went up, it was all over, bye bye money

cars are to blame for about 75% of my debt I reckon.
Hopefully when its all payed off I can save a bit and fook off abroad to travel with a view to a permanent move
