This function watch_video takes the title of a video as a parameter and allows a user to watch the video if they are logged in and meet the age requirements. Here's a breakdown of how it works:

1. It first checks if there is a current user logged in. If not, it prints a message asking the user to log in and returns.

2. If there is a current user logged in, it iterates through the list of videos to find the video with the matching title.

3. If the video is found, it checks if the video has an adult mode enabled and if the current user is an adult. If the user is not an adult, it prints a message asking them to leave the page and logs them out.

4. If the user meets the age requirements, it starts playing the video by printing the seconds elapsed until the end of the video. It uses the time.sleep(1) function to wait for 1 second between each second.

5. Once the video reaches its duration, it resets the time_now attribute of the video to 0 and prints "Конец видео" (End of the video).

6. The function ends after the video is finished playing.

Overall, this function allows users to watch videos if they are logged in and meet the age requirements set for the video. If the user is not logged in, it prompts them to log in, and if the user is not an adult for an adult video, it logs them out.
