How to watch youtube videos without logging in

Some youtube videos require log in and specify your age. You can see these videos without logging in by following method:

Suppose that we want to watch this video:
   youtube.com/watch?v=1LFlYnkRxOo

We need to edit the link this way .

> Replace the "?" after watch with "/" and "=" after v with "/"

> So our link after editing would be:
   youtube.com/watch/v/1LFlYnkRxOo

> Now use this link in your browser to watch the video

Enjoy...
