great but the health feature is useless

When you run out of health, it takes way waaaay too long to recharge. Im at the beginning of learning greek and im making lots of mistakes, to run out of lives does not make me what to continue. Since i have to wait almost 20 hours until its full again, or at least 4, i really dont want to log in again.
