Elvis Was Constipated?!

My friend, Dean is in the know about lifes' important matters because she reads People Magazine. She recently informed me that Elvis died of a heart attack which I did not know, did you? But he had the heart attack because he was, you know, constipated...he was a drug addict and all...and was trying a little too hard to make himself go and bam...dead. I can't believe I lived 50 whole years without knowing this.
