1. Charge an elevator fee? Or make the elevator only function for floors 3 and above while charge a lower price for rooms on levels 1 and 2 where the occupants have to use the stairs instead? maybe the health care awareness works, but I don't see how old people would enjoy that.
2. Are there any more specific information? Like what does the society like? What is the most popular item that they buy?
The co. should advertise the complementary products together with the things that customers buy. If they buy like uhmm... some plasters, then display (what's the name liao?) anti-bacteria ointments like savlon beside the plasters... Advertise them together... like this guy applies Savlon on his cut before plastering that cut... Something like that. So when people got cut, they would go and get the plaster and Savlon at the same time.
Or they can sell more disposable things like disposable socks and tooth brush (for traveling purposes)...
Or do like what some pharmacies do... Give free health check (specialize in something like glucose level, or blood pressure), then say, "Oh, u are marginally below the health level. You can improve your health if you apply this this and that"...
Other than that, I think the co. will have to depend on R&D to discover new effects of the products or lifestyle...
Money is not the most important thing in life. Love is. Fortunately, I LOVE MONEY!!!
