compare to 3 years ago,my body-weight from 87kg to 85 kg.
i lost 2-3 kg of muscle,because of aged 
thats cool man, if those are the stats then so be it. just saying it looks like a lot more deterioration in the 2 pics from 3 years ago.
Surface muscle across the delt/chest area, gone. leg size! woah what a difference.
looks more than 3kgs.
but you're fighting age well anyway.
