THANK YOU....yeah i have been lucky its basically cause i was born thin but could develope a decent muscular build and i followed pretty much same eating plan other when i did a few shows ,i never bulked up fat ever ,i vary only in weight by 5-10 lbs ,i am currently 185 or so lbs...5'7 to 5'8 lol...depending 
What you say goes to prove there is a lot more to looking super fit than can be measured in weight and height. I'm about 5'10" these days and somewhere between 175 and 180 lbs. You're physique is god-like compared to mine. My main excuses are that I am 24 years older than you and bad about training consistency. One thing we have in common is that we both started out lean. Aside from when I was 29 and intentionally bulked up to 225 lbs. for about a minute, my weight is fairly constant like yours is
It is good to know all is well with your heart. It was probably just stress like you said. Stress be gone. It is a bad thing. Very hard on one's health.
Honestly over all the years you have been posting up photos, you look as good as did in your first photo post back in 2011. Here's some reminders of you in the past, including when you were just barely an adult (27).
According to the caption, you were 27 in these photos. Clearly, those were the days my friend... those were the days.
Here you are 48 years old and you have a really pasty face, but the rest of what is showing is killer. LOL!
