The conversation between human and AI assistant.
[|Human|] I am 56, no history of heart trouble, but with many family who have died of health disease. I jog three times per week, and weigh 180 lbs, and have no health problems I know of. Here is the question: I stand on cement in one place most of the day at work. Is this hard on my heart?
[|AI|]  No, per se standing on cement at one place will not affect your heart directly, however two things you may note are 1) as your job doesn't involve an active exercise at the same time tire you enough making you unable to perform recreational sports, its important you balance life towards healthy diet and at least 45 mins of aerobic workout a day .2)n long-standing would make you prone to varicose veins, so consider wearing stocking for the same. Hoping I could help.  Regards Chat Doctor.
