i lost my mom at 6yrs old and my sister who looked after me since then on the 03/11/2012, the day before my birthday, both died of heart failure. Im current overweight and would like to help fund the heart foundation . So for every R1000 i will lose a kilo and donate the full amount to them , please help me remember them with this initiative , if i collect over and above i will also do a full 430km walk in and around cape town as that was my sisters age.(43 years old)
