My aunt and uncle met with my grandparents earlier this week to tell them that they should give up driving.
My grandparents said no.
My mom's right hand has become not very useful. However, she can still use her arm. So I ordered a trackball for her to use instead of a mouse. Overall she liked it. But it stuck horizontally, so it has to be replaced. The company sent one out, without hassle. It should arrive next week.
The tentative plan is to use the trackball in combination with a foot switch to replace the mouse button.
IEEE offers a discount of 50% if one is unemployed! Woohoo! That saves me $120 on my membership for the year!
