La correcta asimilación del calcio
THANK YOU, my favorite "DuoBot", for uploading this very interesting article. (If you were a real person, DuoBot, I would give you a hearty slap on the back!)
That said, I invite everyone in the Duolingo Community who are "into Spanish" to read this interesting article. It is very informative and is quite straightforward (with few twists and turns): in other words, it is not an extremely difficult "read".
And, after all is said and done, I recommend doing what the article says to go out and do. (sunglasses optional) :)
