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.
Ako imate rak mozga i kažete da se od dubljenja na glavi po 20 minuta svakog jutra  bolje osjećate, to je moguće, ali i dalje imate rak mozga i vjerojatno  ćete ipak umrijeti od njega.
