Living Is a Problem Because Everything Dies

"Living Is a Problem Because Everything Dies" is the opening song on Scottish band Biffy Clyro's fourth album, Puzzle. It was released on 14 May 2007, as the second physical single from the album. The song itself, without any B-sides, was released as a digital download on 7 May 2007.

In the week after its download release, but before its CD release, the single reached number 72 on the UK Singles Chart before peaking at number 19 the week of its release. The same week, the song became the band's second number-one single on the Scottish Singles Chart, after "Saturday Superhouse". The song was the first single released by the band in the United States, and was the first single released there for Puzzle. It was added to the playlists of several radio stations in the United States—including WBRU, WQEX and WHHZ—which allowed the song to reach number 47 on the Mediabase Alternative Airplay chart.
