I'm going to be a little contrary to others in this thread. Frankly, I think this type of thing IS normal. 48 and you need a nap, I've taken a nap every day of my life. Tinnitus? I've had tinnitus my entire life. Both ears, even when I was 4 years old when I didn't know what it was.
Everybody has SOMETHING! My mother had Grave's disease when she was 40. Who gets that? My father had prostate cancer. My stepmother had lumps in her breasts that had to go and skin cancers that had to be cut out. My stepfather has to take rat poison every day for his heart. My mother-in-law had half her thyroid taken out, my previous MIL had her entire thyroid cut out. Manic depressives, addicts, seizure disorders, Traumatic battle injuries, people I had coffee with that were shot to death the next day, my playmate at age 5 who crashed and died on his bicycle, a teenager with pancreatitis, autism, ALS (Lou Gehrig's Disease), multiple sclerosis, it goes on and on and these are all people I know personally.
