Phinda amakhilogremu ngo-2.2 ukuze uthole amaphawundi. Umuntu ongu-70 kilogram ulingana cishe namaphawundi angu-154. Lokhu kuwusizo ekuhloleni imikhawulo yesisindo semithwalo, evame ukukhonjiswa ngamakhilogremu ezikhumulweni zezindiza zamazwe ngamazwe kodwa ijwayeleke kakhulu ngamaphawundi kubahambi baseMelika nabaseBrithani.
