Items you cannot live without

Well yesterday our air conditioner died on us and we have to replace a part. which is not the bad part, but we are having high temperatures right now . yesterday was 100 degrees . I was so uncomfortable it was insane , talk about a heat wave .

So I guess with that said , my question for today is what can you not live without? I thought smaller things a while back but since yesterday and being in the heat all day, what I know cannot live without is air conditioning .

Take care and have a great day
