No I'm not jealous. But one friend constantly posts pictures in a state of undress. I get that they are into the gym and that but today they've just posted "I work full time during the week and bar shifts at weekends, there is no excuses"
Apart from they are single , no children, no dependants, they work as an estate agent (not exactly rocket science), don't have a garden, don't need to help out their family and they have always been in good shape,probably due to genetics etc.
