Hello there,
When I said 'first hand experience' I meant it.
I have a close friend of mine who is practically blind (cannot read a single character on the test chart) with one eye. He was able to obtain his driving license without any issue here in Germany. Needless to say he had to go through additional examination than regular to prove that the good eye can compensate.
In the process he got to know many others in the same situation and he shared the news with me. So this is not an isolated incidence either.
Therefore this is a real life concrete fact! No amount of your google searches can disprove it!
Example of cricket was to stress the human body's ability to adapt to the nature's demands as several others too did on this same thread, which apparently you fail to comprehend.
But I know this is my personal experience and others might not find it so useful. Hence '2 cents'.
But it seems your google searches are worth 2 millions to you.
I don't want to argue about my '2 cents' .
I am sure you will find somebody else to argue with about your '2 million-worth' google searches.
