Gambling Study

Evening gents, I'm doing a study on gambling for my project at uni. Was wondering if you could answer a few questions for me. Will only take 2 mins.

I would like to know:

1) How frequently you bet on sports
2) The number of different sports you bet on
3) The number of years you've been gambling for
4) How much you stake on an average bet
5) Your total profit (or total loss) for the past year
6) Your total profit (or total loss) since you started gambling
7) Do you usually bet with bookies, exchanges (such as betfair), or both?
