If you find these things a bit non-involving for the body, I can also suggest you some tangible stuff. When you are at one place, you can learn the art of building belly-fat! Feel blessed to be not moving. Assume danger in any motion. Just sit there. Lie there! Just keep working your fingers around your waist and feel the fluffy, spongy stuff! Why does everyone always think of muscles? After all, fat is also a ‘biological’ element. We respect anything related with that adjective, don't we! Who knows; some day being fat may become fashionable! You will need the experience then!
People say that one should look for opportunities every time. So, I took this opportunity to guide all of you there to just looooooooove your laziness! To not feel guilty about the ‘sit-and-do-nothing’ phases in life! I do have more ideas but I can’t share all of them together. Sparing some of them for laziness’ sake!
