"My brother is older than I" should be added. See, for example, http://www.grammar-monster.com/lessons/than_I_me_than_he_him.htm
"ode" is used when using "od" would be unpronouncable. Which, if I am correct, happens literally in two situations:
"ode mnie" = "from me"
"i zbaw nas ode złego" = "and deliver us from evil" (actually you can say "od złego", but the prayer just preserves an older way of writing)
Ha! Caught a spurious You missed a space error triggered by brother's. But they're getting rarer :)
