If a person thinks there is no afterlife, why should he choose to be righteous?

I have seen people resort to arguments such as "if there is no afterlife, why be good (or religious)?". Counterarguments to living in sin during this life include final judgment and the infinite duration of eternity (which also form the basis of Pascal's Wager ), which I find compelling, but are there more reasons to be good than these? What Christian denominations advance an argument that is persuasive in favor of doing good in this life even if one thinks there is no afterlife, and what are those arguments?
