My mom is getting up there in age (74) and lives alone after my dad passed away last year. She's already had one knee replacement and is looking into the other. She has had a few falls over the past several years but we've always had in home health care for my dad. She also has a dog that can sometime get in the way. I am looking for a medical alert system bracelet but there are a lot of options out there. I know she won't want to wear anything to bulky. Also, it appears these have a home base in the house. Is there any value to wearing it while away from the house? If not, how do you encourage it be put on as soon as they are back at the house? TIA
