Is it my fault?

It's incredible, when the weather turns hot I change my clothes, (put away the shirt , the tie, the sweater and wear t-shirt, polo), like probably everyone in the world.
Well, why is it that after only one day my back feels  like wood, my neck is  shouting at me “use your scarf!”.
Is it  the fault of Global Warming or does it depend on my age?

Really good work Roberto. Please note that we don't tend to say "the shirt" etc when referring to our shirt - instead "my shirt". I've also reworded your final statement to sound more casual and simple :)
