Boring Cardio ?

I read a few blogs on fitness health and  weightloss .Many of them offer really good advice; up to date information on how to get fit and stay healthy . The current trend seems to be away from continuous"cardio" ie excercise that raises ones heart rate and therefore improves cardiovascular health. and towards strength training and H.I.I.T. ( high intensity interval training) . The feeling is that prolonged moderate exercise e.g running long distances, causes inflammation , overuse injuries and doesn't in the long term promote weight loss or good general health . There seems to be sweet spot where exercise increases  cardiovascular health but doing more and more aerobic excercise actually decreases the benefits to one's heart . H.I.I.T. involves very short bursts of about 30 seconds of maximum effort with a short interval between.and this appears to be the most effective way to get fit and to burn fat .Strength training increases muscle and counteracts the age related drop in muscle strength .
I take this on board ,  The science  suggests that ultra running may not be good for you.
However I draw the line when some well respected health gurus talk about 'boring cardio' as in  "You don't need to do all that boring cardio just follow my training regime for 15 minutes a day." This really annoys me; I want  to do all that "boring" cardio.
 To me cardio is no more boring than breathing . 'cardio ' or at least running all day in the hills has given me most of what I love in life .
It is through hill running  that I met my wife and from that first day our relationship has flourished through our shared passion of running. It has helped me though some  difficult and  lonely times in my life. Years ago when I was working very long hours including every other weekend  on call, I would never have coped if I didn't spend all of my time off running in the mountains. I think that running has given me more pleasure and  periods of intense joy than any other activity I have ever engaged in. It has made me who I am, it has shaped and  coloured my life.
Boring  cardio ? If you're bored with cardio you are bored with life!
