I am a visitor with a question ....

I want to ask about kitchen design. My husband is going to be in a wheelchair (progressive MS), and I have started looking at the world differently, finally. We are doing some renovations, and want to know if everyone has kitchens designed to them, ie) lower built cabinetry, sinks and cooktops. I always thought that I was observant, and am figuring out that I'm not...or we only observe what is within our realm of experience. I have started noticing accessibilty everywhere I go, and its started to peel back some layers for all the types of people we have in the world.... Tell me things about life in general, and why there aren't more sideways opening ovens!!? Much more safe, no?
