and this one was in march last year (nearly one year ago) and i was 75 kg or so.. so mr. gronk sees me old at 32 while i was not at 31!!!!.. 
Face it Sharief....you can post every old picture you ever took.
Doesn't change the fact that your metabolism is really starting to slow down, that's what happens when we age...and there are no "warning signs".... it just happens. That's life.
It's obvious that's what is going on here....you haven't posted an ab shot in well over a year and now we know why.
You can get mad at me and call me an "asshole" all day long, you know as well as i do that i'm right.
I'm 45 dude...been there. One day you can eat whatever you want,....the next day you're like "hey...WTF ??...I'm getting FAT"
And let me guess...back in the day if you wanted to drop weight it was a snap...watch what you eat for a week and BOOM, right where you want to be.
Not anymore...right??

welcome to your thirties...."Kid"
PS....your pics are older than you are saying they are...for example, last march isn't "almost a year ago"
