Women: we are his voice of truth. If you notice your man is dragging a foot when he walks, bring it up. If you notice he doesn't breathe for 30 seconds when he sleeps, voice your concern. If you notice he's suddenly dropped a LOT of weight due to his new medication, ask him how he's feeling about his medication. If you notice he needs a moment to gain equilibrium after standing up, ask about his blood pressure.
All of this is based on real life, based on my (and The Loud's) life. Be the hero, don the cape. Love you all.
7/5 edit/clarification: Apparently this was alarming as written, and I never meant it to be! The Loud has dropped quite a bit of weight lately due to a change in his diabetes meds, and I initiated a frank discussion with him about it, mainly to keep those lines open because otherwise he won't talk much about what's going on with his body. A month ago I noticed he'd have to take a pause when standing up from his chair, letting the lightness in his head settle down before he dared take a step. I brought it up and that discussion led to the probability that his new blood pressure meds are probably too strong (107/68 is way too low for a man in his 70s). Starting that night he's been splitting the pills in half, and will bring it up with his doctor at tomorrow's appointment.
