My main computer is a 15 inch retina macbook pro from 2013. I use it a lot (roughly 10-12 hours/day) so it's plugged often. It always gets quite hot next to the magsafe connector so what happens every time I buy a new charger is this: - the part of the cable next to the magsafe connector becomes yellow from the heat - the yellow part of the cable starts to become less resistant and kind of flakes - Eventually the wires are exposed. This takes about 1 year, 1 year and an half. I never jam it in doors or desks. I do not have pets. I sometimes put it in my bag but I do not wind up the cable to avoid having additional tear on it. I do live part of the year in hot and humid climate (like Japan in summer or South East Asia) which might accelerate the issue. But honestly, this is a problem, no matter how careful I am, I have to buy new chargers.
