How do you destroy financial records?

I am shredding records from my mother's estate that are more than seven years old. I had a stack of canceled checks, medical bills, receipts, medicare statements, tax records, you name it. Anything that had her financial information, bank numbers, social security numbers on it went into the cross-cut shredder. It has taken me all afternoon, because the shredder keeps overheating! And I'm thinking that I haven't done my own old records for a while. I probably should go through them. What about you? How many years worth of tax papers, bank statements, canceled checks, etc., have you accumulated? and how do you plan to get rid of them?
