making life easier

When I first got here in the states, Everywhere I go I see senior citizens with portable stuff with them like a portable oxygen concentrator, electric handicap carts, And just about anything you see with them. Even though they have an illness nothing seems to stop them from going out and live a normal life. It's very nice to know how people can come up with stuff like these that can help us in our every day lives especially for the elderly and handicapped. I salute those people who made every contraption out there that can make our jobs easier and better.
