My grandfather is 84 years old, 6'-2" and 185lbs

He weighed 193 last year.

He works 30-35 hours a week at our family business and his mind is sharp as a tack.

He recently has started dragging his feet when he walks I fear a fall will be the beginning of a downward health spiral for him.

I want to push him to an androgel product but know he will be a tough sell, likely along with his current doc.

Would I be right in trying to sell him on this?
