When para-swimmer Satendra Singh (30) dives into the sea today, it's won't be to cool off but to warm up instead. Singh, who was paralysed from the waist down shortly after his birth due to glucose water rejection, will swim 30 km off the coast of Mumbai today, before he departs in June to try and conquer the notorious English Channel.
