My 95.5 year old father is big on taking lots of vitamins, minerals and trace elements.  Since he was 93 he's been taking blood pressure and cholesterol meds...result of finally being shaken up by a mini-stroke which luckily had no lasting effects.  He was always big into vit C and E and after 65 began to take a lot of the other reputedly good vitamins, etc.
Anyway, he almost NEVER has an ache or pain and has not had any serious health issues beside high BP.  He is still plenty active for his age (walks a mile daily and often takes his own fishing boat out for a day of fishing) and is also still very sharp and alert mentally.  He swears by the vitamins and his doctors tell him what ever he is doing seems to be working and he should keep it up. 
Some holistic friends of his often discuss the detrimental effects of a diet high in processed wheat and sugars and the balance of acid/base level of one's overall system.  They blame a lot of aches and pains on being "out of balance" chemical wise within one's body. 
I agree that more attention should be given to the natural foods and ways one can keep their body healthy as opposed to modern "medicines".   :)
