i Work really hard for 18 hours a day.
Your post is somewhat vague - You say you work really hard for 18hrs a day but you do not say what you do. If you did a manual job for 18 hrs a day I would think you would be collapsing with exhaustion and when would you eat, drink and sleep if this was the case? I am trying to work out what type of employment would engage you for 18 hrs out of 24 hrs - it is surely against the law? There are lots of factors which can cause a person to be obese - it can be caused by over eating/drinking and insufficient exercise or a combination of both but it can also be caused by lots of other factors such as health related problems and even genetics.
Well, thanks for your candid advice. It was a close pal that asked me that question and i thought of sharing it here. The truth is that she is a Freelancer and she works as a Virtual Assistant for a very busy man. I already gave her some advice.
