You Don't Need To Do Anything But Be Born And Die...

...Anything else is entirely your choice. If you haven't been getting blood drawn regularly every year or two as part of a regular medical check-up, then that has been largely your choice as well, although I don't know anything about your life including employment, finances, medical insurance, etc.. Health is at the top of my priorities in life, but I won't assume that is true for most people I meet. So, personally, I would certainly have a blood work-up, with an emphasis on liver enzymes, along with a complete physical, and I'd inquire about whether [s]he recommends an endoscopy to check the condition of my esophagus (checking the blood vessels as well as early signs of esophageal cancer). But again, that's just me, and I am not giving medical advice since I'm not a licensed medical doctor.
