It's true as a Venezuelan I also experience everything you mention in your post, and it hit me very hard, after being a person, in good health and very robust, I am now too thin. Everyone who knows me is surprised to see me at first hit me a lot, but I'm used to total I'm not the only one. I have also had to walk with my knee problem but what can one do, wait for a bus stress because they are scarce. I loved your post, my friend Alfredo, I know that you have also stuck all this very strong, but mood of the storm always comes the calm
