Demo, I think t/b a senior actually starts earlier maybe late 50s. But young senior will cover it, unless you'd prefer 'teenage senior'. On my hand I am older than you by . . . . years. It's a great time in life for learning new things. I took a disability retirement from workplace injury, so got medicare immediately. But when you're 65, sign up for medicare even if your wife still has medical coverage. Medicare doesn't cover everything and you'll still need a supplemental plan for what it doesn't cover, so keep your's or her's - workplace coverage seems better than the other supplemental plans out there. Build up that retirement plan as much as you can, SS $ helps, but you certainly can't live on it. There are other sources of $ in retirement like: investments, savings, pension, interest, etc, or working. So if you or she really likes your job, keep on working or do part-time like you are doing. Hopefully your health problems aren't to serious or debilitating and you can still do part-time, or find/learn something you enjoy more.
Back to problem child - me. I got a message on my phone that it isn't backed up and I need t/b plugged in (which it is) and connected to Wi-Fi (which I can't). Don't worry I searched around and know what to do, but have to 1) get to the charge plug - it's behind a file - then plug it into the computer; 2) sign into Wi-Fi - can't until I gather necessary info. We use a router (Verizon) - I need it's IP, user ID, password, etc. You get the idea - all that info my husband has in files somewhere (maybe). Anyway, the best option w/b to retrieve the plug from behind the file cabinet UGG! So will attempt that later, unless good football games are on today. I have to sync computer when I get wall plug, too.
Also, I clicked on your link for manual/user book. I think it's the one I downloaded when I first got this confusing 'smart phone'! That book is so confusing! Yes it has index and chapters for this or that, but when you get to what you want to do it refers you to a different page, which refers you to a different page. So very frustrating - who wrote it anyway. Also, in your link I didn't see an option for download. Be well, be happy, Trish - I'm going to miss you when I get my music/phone problems solved.
