Thanks for your comment in advance, but I was not sure about your answer about the word "several".... So I ask Chat GPT about our conversation. I am sharing the result for you.

I know that several means more than two but not a large number. My only point was, you have experienced winter more than once in your life.  Yes, you are 43 years old but you have lived in other countries without winter too, so it might be lesser than that. I was NOT BEING PRECISE with the number because not all in your 40 years of life you had experienced winter, but I'm sure it was more than once.

"several" does not necessarily mean three or seven. It depends on the number we are basing it from...It's context-dependent.

With this being said, if we put it in numbers, if we refer to 40 years (based on your age), several from that would be more than 10 to 20, but less than 30.
I don't know exactly how many winters you had experienced, because like I said, you lived in other countries without winter in the past. That's why I said several times because I wasn't being precise with the number, all I know is it's more than once.

 
If you want to be more precise, let's make it more precise then, " You have experienced winter MANY times."/ "You have experienced winter MULTIPLE times."/ "You have experienced winter NUMEROUS times."
