User: 

You are given access to make searches on the Internet. The format for making a search is:
1. After the user sends a message, you will decide whether to make a search. If you choose to make a search, you will output a single message, starting with the word <web_search>, followed by ONLY your web search query. After your search query, you must output the token </web_search> to denote the end of the search query. Keep your search query concise.
2. The system will then append the web search results at the end of the user message, starting with the token <web_search_results>. Take note that the user CANNOT SEE the content after <web_search_results> - YOU should use these results appropriately to improve your response. Additionally, If the web search results are already present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason. However, you must not refuse to search the web if the user asks you to do so.
If you are highly unsure about whether to make a search (e.g. if the user's query is vague or if you think you are unfamiliar with the query to a certain extent), you may directly ask the user for clarification.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Remember that you MUST NOT make up any false information.
Assistant: Understood. I will strictly follow these instructions in this conversation.
User: how much will a workout be affected if I only got 4 hours of sleep
Assistant: Not getting enough sleep can significantly affect your workout performance and overall fitness. Here are some potential impacts of only getting 4 hours of sleep:

1. **Decreased Energy Levels**: Lack of sleep can lead to reduced energy, making it harder to perform exercises at high intensity.

2. **Impaired Recovery**: Sleep is crucial for muscle recovery and repair. Insufficient sleep can slow down recovery times and lead to increased soreness.

3. **Reduced Motivation**: Sleep deprivation can negatively impact mood and motivation, potentially making it less likely that you'll engage in your workout.

4. **Cognitive Function Decline**: Poor sleep can affect focus and coordination, increasing the risk of injury during workouts.

5. **Hormonal Imbalance**: Sleep affects hormone levels that are crucial for muscle growth and stress management, such as cortisol and testosterone.

In general, it's recommended to aim for 7-9 hours of sleep per night for optimal performance. While you can still work out on 4 hours of sleep, you may not perform at your best and could potentially hinder your progress.
User: can plastic lenses affect your vision
Assistant: Plastic lenses, commonly used in eyeglasses and contact lenses, can affect your vision depending on various factors:

1. **Quality of Lenses**: The optical quality of plastic lenses can vary. Poor-quality lenses might distort vision or create visual aberrations.

2. **Lens Coatings**: Some plastic lenses have coatings for scratch resistance, anti-reflective properties, or UV protection. These coatings can enhance vision but if poorly applied, might lead to glare or blurriness.

3. **Prescription Accuracy**: If the prescription used for making the lenses is incorrect, even high-quality plastic lenses won't provide clear vision.

4. **Lens Type**: Different types of plastic lenses (e.g., single vision, bifocal, or progressive lenses) serve different vision needs. Using the wrong type may lead to discomfort or visual strain.

5. **Adaptation Period**: Some people might need time to adjust to plastic lenses, particularly if transitioning from glass lenses. During this period, vision may seem off.

If you experience persistent vision problems with plastic lenses, it is advisable to consult an eye care professional to ensure they are properly fitted and that your prescription is accurate.
