Once you pass the magic age of 50, stuff starts going wrong with your body according to what seems like a pre-planned schedule. Going to the Doctor about some problem usually ends with an explanation of the cause and the phrase "..it is normal at your age.." or "..this usually happens in your 50's". They should have an app where you can plug in your symptoms and it suggests the likely age-related cause, except some lawyers would probably sue the developer.
My latest afflictions are a pinched nerve in the neck caused by aging of the spine and a vitreous detachment in my eye that is causing me to see spots and cobwebs all the time. Both will go away (hopefully) with some time and/or treatment. In the meantime, they provide a convenient excuse for not finding a part time job or lifting heavy objects.
