I want to be healthy

Second week into 2010 and I'm sick once again. I seriously have to change my life style to a healthier one. Must sleep earlier! I realise every time after I burn midnight oil, few days later for sure I'll suffer sore throat and flu and then there goes the list. Yeah, according to Chinese physician, my body is the 'heaty' kind. Knowing this and yet still doing it is really 'stupidity'. I guess I need to do some exercise too. Exercise as in real exercise and not dance practice every week. Need to sweat so that can 'detoxify' my body. Am thinking of starting a nutritious plan maybe sometime later to balance my body back. I want to be healthy!!!
