2015 was, for me, mostly just an extension of 2014 in this regard, as I had a big &quot;life altering&quot; experience late in 2014.  I had a heart-attack in November 2014 and could well have died.  Luckily I live close to a good ER and what-not and got prompt treatment and I&#x27;m mostly fine now.  I&#x27;m on a bunch of new medicines, but otherwise things are mostly back to normal. I did some mountain bike racing this summer, before I tore my rotator cuff in a fall and switched to mostly road cycling until I get my shoulder fixed up.<p>Soo... to answer the question... and hopefully without sound to glib, I&#x27;d say &quot;take your health seriously.  Stuff creeps up on you&quot;.  That is, all the warnings you hear about &quot;eat right, exercise, keep your cholesterol down&quot;, etc... yeah, that stuff does matter.  And yes, it can happen to you.  I know, because I was one more person walking around thinking &quot;that stuff only happens to other people&quot; until I was on the back of an ambulance wondering if I was going to die.<p>I really don&#x27;t like being the preachy type, but if I have any useful advice to share, I&#x27;d say it&#x27;s this... invest in taking care of your body.  And by &quot;invest&quot; I mean, time, knowledge, money, exercise, food, whatever elements you need to leverage to maximize your health. Read a book like <i>Cholesterol Clarity</i> and understand how this cholesterol stuff really works.  If you&#x27;re a little overweight (or a lot) find a way to start getting more exercise.   Buy a bicycle, or a skateboard, or a surfboard, or just some comfortable walking shoes, whatever.  Throw out the Doritos and sugary sodas and shit.  Learn to eat healthy.  Quit smoking if you smoke.   That sort of thing.
