I have observed and experienced the way IT engineers and many other similar professionals are working a lot, spending nights and day, constantly hooked onto laptops, many of us are losing a lot of hair, have dull skin and face a lot of other issues.
There are a lot of issues that we don't observe like fatty lever, cholesterol, vitamin deficiency, back problems and many more. These problems don't surface in 4-6 months or a year. They will be there when we maintain unhealthy lifestyle over couple of years.
Have seen people in 35 looking like 50 with grey hair, dull skin and unhealthy. Have seen a lot of people spending day and night on laptop voluntary even after having kids. I am 100% sure no family would want to see you guys working all night. What these people will tell their family is I have a lot of work when it's not the case
