Google docs while checking grammar may detect that it is a wrong word based on context of the sentence.
It saves me whenever I mistype then/than with 100% accuracy.

Just remember to...
use google docs and set it to either British English or American English.
It is really good tool in correcting spelling and grammar.
But beware of words that are different only by one letter
have/gave
dog/hog
how/now
Those might be picked up or may not depending how strongly they would make...

Yvae Yvea
Salih Shila

My two top guesses to have "whole lot of people" after your life would be Ukrainian soldier or tax collector.
