If you have brain cancer, and you say that standing on your head for 20 minutes every morning makes you feel better, it may make you feel better, but you still have brain cancer, and you'll still probably die from it.
Se você tem câncer no cérebro, e diz que ficar de ponta-cabeça 20 minutos todo dia faz você se sentir melhor, talvez se sinta melhor, mas ainda tem câncer, e ainda poderá morrer.
