My friend's elderly mother was taking various prescribed drugs for ages. Her GP retired, and the new one called in all the elderly patients for a 'medication check.' After consulting her, and her medical records, he declared, "You don't need that, or that, or that!" She is now on minimal medication, and her mental alertness and general health have improved.
As for me - I question anything my GP wants to put me on, and have resisted his efforts to take statins. My heart, cholesterol levels and blood pressure are all fine. He once grumbled that "The graveyard is full of people like you!" but I am almost 79, medication free, fairly fit and active, and a darn sight healthier than most of my contemporaries.
I would rather drop dead of a heart-attack anyway, than moulder away from dementia in a nursing home!
