Patapita nthawi, makina opumira anafika mosavuta kwa anthu ambiri. Anayamba kuwonekera m'malo ochitira masewera olimbitsa thupi komanso m'malo ochitira masewera olimbitsa thupi, ndipo anthu okonda masewera olimbitsa thupi m'nyumba anayamba kuwonekera. Masiku ano, makina opumira ndi chimodzi mwa zida zodziwika bwino zochitira masewera olimbitsa thupi, zomwe anthu mamiliyoni ambiri padziko lonse lapansi amagwiritsa ntchito kuti akhale ndi thanzi labwino.

Koma n’chifukwa chiyani ma treadmill akadali otchuka kwambiri patatha zaka zoposa mazana awiri kuchokera pamene adapangidwa?
