- Kafukufuku waposachedwa awonetsa kuti m'madera omwe mulibe mankhwala ochepa, milandu imachitika kangapo poyerekeza ndi zigawo zomwe zimakhala ndi lead yambiri. Pali malingaliro omwe amatsogolera amakhudza kwambiri ubongo.
- Kodi mumadziwa kuti palibe mpweya wosungunuka mtovu, ngakhale utakhala wamadzimadzi?
