Hey! Do we really need recreation or leisure time to function as humans? Could one get away with it and just work all of his life to whatever purpose he/she is set to go for? How does one distinguish between work and leisure time? Was there such a distinction in early humans? Or did one such distinction develop with the evolution of societies? I'm full of questions I know! But I couldn't find any reliable resource over the internet. Most were on the lines "Recreation is something you need to refresh your soul!"
