Just a bit of advice to all waiting! My husband is 3 weeks after triple bypass surgery. he spent the 16 weeks waiting getting fit for it and what a difference it has made. He walked 15000 steps a day, gave up drinking and lost at least 12 kilos. He is 9000 steps and getting better, eating well and healthily, working 3 mornings a week (job requires) and whole family heaving a sigh of relief! Life has changed for us all and only for the better!
