We present a new, simplified analysis of the low-energy electron-positron interaction, and use the resulting effective theory to calculate the binding effects that contribute to the decay rate (Formula presented) of orthopositronium through (Formula presented) We express the total decay rate in terms of the annihilation rate for a free electron and positron at threshold, which has just recently been computed to sufficient precision. Our (Formula presented) result corrects errors in a previous analysis.
