Going Senile at 30: Question on Stack Exchange

In summary: No, there isn't. Yesterday I posted a question on Stack Exchange that was so trivial that I think I might be going senile at the age of 30. That, or I was under the influence of something.Does $\lim_{R \to \infty} \int_{C_{R}} e^{iz} \ dz \to 0$? (Drunk)

Yeah, I must confess , that wasn't easy to see at the first glance, at least for me. I was trying just like you to find an upper bound (Headbang)

Well, I guess I am going senile at the age of 23 (Worried)

And then mrf had to rub it in by mentioning that $e^{iz}$ of course has an elementary antiderivative that is valid everywhere since $e^{iz}$ is an entire function.

I could have at least recognized that there was no justification for bringing the limit inside of the integral due to the fact that parametrization of the integral brings an $R$ out front.

Actually, it isn't always easy to see that a function along a contour approaches zero for large or small quantities of the modulus. It is always the hard part when using complex analysis approaches.

I recognized that the function has an anti-derivative but that was a little bit late .

I went senile already. Wasn't working for me.

If You allow an 'oversixty' to do You a suggestion, then the suggestion is...

... sometime just take it easy! (Happy)...

Kind regards

I am already senile at 13. I once thought about a long time why there is no prime $\geq 3$ of the form $x^3+y^3$. :p

Yes you are, since you are now 14. :D

Ah, but I will refer myself as 13 ever afterwards until 17, as 14 is not of my likes, neither is 15 or 16!

I guess if Jack Benny could be 39 forever, then you can be 13 for a few years. :D

I'm in my mid twenties and often feel I'm just not as sharp as I used to be. Doesn't bode well for my 30's and 40's. :p

True. Working with some complicated stuff , you always miss the trivial. Sometimes it needs no more than thinking simple to find the solution.

That's why I drink so much- so I can claim I'm not senile.:p

Is there a converse of Morera's theorem? (Smirk) :p
 

FAQ: Going Senile at 30: Question on Stack Exchange

What is "Going Senile at 30: Question on Stack Exchange"?

"Going Senile at 30: Question on Stack Exchange" is a hypothetical scenario that poses the question of whether or not it is possible for a person to experience early onset senility, or cognitive decline, at the age of 30. It is a popular topic of discussion on the online platform Stack Exchange.

Can a person actually go senile at the age of 30?

This is a highly debated topic and there is no definitive answer. While there have been cases of early onset dementia or Alzheimer's disease, it is not common for a person to experience significant cognitive decline at the age of 30. However, factors such as genetics, lifestyle choices, and underlying health conditions can play a role in the development of cognitive decline at any age.

What are the signs of early onset senility?

The signs of early onset senility can vary from person to person, but some common symptoms may include memory loss, difficulty with problem-solving and decision-making, changes in behavior or personality, and difficulty with language or communication. If you or someone you know is experiencing these symptoms, it is important to consult a medical professional for proper diagnosis and treatment.

What are some ways to prevent early onset senility?

While there is no guaranteed way to prevent cognitive decline, there are some steps you can take to potentially lower your risk. These include maintaining a healthy diet, staying physically active, engaging in mentally stimulating activities, managing stress levels, and staying socially connected. It is also important to regularly visit a doctor for check-ups and address any underlying health conditions.

Is there any scientific research on this topic?

Yes, there have been numerous studies conducted on the topic of early onset senility and cognitive decline. However, the results are inconclusive and more research is needed to fully understand the causes and potential prevention of cognitive decline at a young age.
