@Geektastic I wear my Apple watch to bed and monitor my sleep. I use it to track my exercise and movement something I have found very beneficial. It could be too easy to sit and do nothing but the watch and targets keep me motivated. I have a history of bouts of AF so having the ability to maybe detect that is comforting as well as the fall detection.
I also use to to unlock my iMac. When I am in my wheelchair it is a godsend for checking messages, emails, security alerts and answering or ignoring calls without the battle of trying to retrieve my phone from my jeans, trust me that is a mission in a wheelchair. Also if I have left my phone in another part of the house I don't need to try and rush to it and risk injury. I charge my watch every day once a day but could easily go longer. When I am ready to get up I put it on charge have my shower and get dressed and by then it is charged. Granted I do take longer than most to complete that task.
