Spent my Saturday helping do yard work at my 99 yr old Grandmothers farm house with my 72yr old Dad and his 58,59,70,75,78,80,80,82, yr old brothers, sisters & in laws, we worked for about 6hrs with a lunch break and the only one that slowed down was the eldest brother who was sick.
If the other half Grandma's kids had shown up it would have been a breeze.
