you mean cosas with s 2 is plural
he or she did two things in his or her life
For it to be correct Spanish, this sentence fragment needs to say, "...dos cosas que hizo en su vida. " Nouns and verbs have to agree in number and gender in Spanish. It means, "...two things that you/he/she did in your/his/her life." Without a definite context, the pronouns are equally interchangeable. So, it could just as easily be "...two things that he did in her life." as "...two things you did in his life." etc.
