Update is terrible

This new update with the health thing is the worst thing youve ever done to the app. I used to spend hours a day on Duolingo but now I cant because I will run out of health because I made a typo and got the answer wrong on accident. The only way to refill my health is to use lingots which I have to buy with real money. Im trying to learn Spanish quickly since Im going to Spain in two months but this is slowing me down big time. Please fix.
