How do you deal with unsolicited advice of relatives?

Why do relatives feel that they should always talk about doing things the right way and how do they know what they say is the right way? Some examples - - to lose weight, focus on walking and fully come to normal BMI and then only do weight training. But, research suggests weight training to be more beneficial for both weight loss and increasing metabolism - we should drink hot water to lose weight. What?😂 - get married early and marriage is the only way to go! - our screen time shouldn't be more with mobile, but rather with tv - don't use earphones, they damage ears - Some fruits are beneficial for diabetes Don't get me wrong, I love relatives. I just don't enjoy someone giving advice when I didn't ask them. Especially when I can't trust their source of information for anything - life advices, religion, shastra, traditions, women's rights etc. And, I am really tired fighting battle and tackling so much misinformation about everything. All I do is just listen to them and move on! Wanted to know what do you guys do?
