Did you perhaps mean "purpose" instead of meaningful. Having purpose makes life meaningful. And yet, purpose is not dependent on physical or mental attributes. For example, my wife's 20 year old cousin with who has cerebral palsy(motor skills mostly ok, intelligence level of a 10 year old) is a curler in the Special Olympics and recently won the provincial cup. She has purpose in life but if I understand your position correctly its not meaningful because of her disability. Another example. I coach tykes football. I like having the younger kids and watching them learn and develop over a few years of ball. Every year we get new kids and every year we get one or two with varying degrees of ASD(obviously mild) or ADHD. And the one thing we agree on as coaches is to treat them all the same. Its amazing how much gaining a little confidence coupled with strong, steady reinforcement from a non-relative can go a long way in helping a child. I guess my point is that everyone can be given purpose in life. People shouldn't be shuffled away somewhere out of sight because they make us uncomfortable by reminding us how we won the life lottery and they didn't.
