WMG / Cells at Work! CODE BLACK

The body belongs to a recently-divorced middle-aged Salaryman.

Being middle-aged would make poor health more likely due to age, so crises hit hard; being a salaryman would contribute to ongoing stress, given that the spikes we see are noted as being 'even higher than normal,' and explains why the stress is chronic. Salarymen often have poor diets due to grabbing meals when they can and that, plus post-work drinking, brings down general health. The recent crisis is a result of the divorce: It's noted that he stopped smoking ten years ago but started again, so he likely stopped when he met or married his wife and resumed after she left. His poor hygiene and lack of self-care stems from depression resulting from the divorce and his poor diet is a mix of indifference and an inability to cook, as many Japanese men rely on their wives for meals; plus, excessive drinking is frequently a sign of depression. His erectile dysfunction is caused by depression as well as stress, as it's noted that erections "used to be more frequent," as in when he was still with his wife. Her departure also explains the unsafe sex, probably with a prostitute given that it resulted in an STD. Plus, heart attacks are a stereotypical risk for salarymen.
