You must spend a lot of time reading legal documents then. Damn near everything involves me signing something saying that I can either get sued or can't sue over something.
I don't think it's that many. This year I signed a new credit card contract, contract extension with my landlord, mobile phone contract, some online service direct debit signup and a car rental paperwork. That's it - and I read all of that. I'm not sure a typical person ever goes over 10 things to sign a year... It's not that many and it really pays off to read them before you sign.
