I cant wait for the day when I am going to turn 30. If not for others, at the least, I will start taking myself seriously. :(( Right now, I am neither young, nor old. So, you know no one’s gonna look out for you, but at the same time, you don’t feel the need to be responsible either. :D

Live it up, I like to say I am 30... but only since last 4 years

no wonder my last thesis defense was labeled "un-inventive, lacking zeal"... i so do hope this is not true, even though in my heart i know its true. most mathematicians do their best work before the age of 24, and if by that age, something of considerable substance has not been achieved, little would come later... not my words mind you, those are Pierre de Fermat's words.

Mental powers start to dwindle at 27 after peaking at 22, marking the start of old age, US research suggests. Professor Timothy Salthouse of Virginia University found reasoning, speed of thought and spatial visualisation all decline in our late 20s. Therapies designed to stall or reverse the ageing process may need to start much earlier, he said. His seven-year study of 2,000 healthy people aged 18-60 is published in the journal Neurobiology of Aging. To test mental agility, the study participants had to solve puzzles, recall words and story details and spot patterns in letters and symbols. The same tests are already used by doctors to spot signs of dementia. In nine out of 12 tests the average age at which the top performance was achieved was 22. The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability. Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60. Professor Salthouse said his findings suggested "some aspects of age-related cognitive decline begin in healthy, educated adults when they are in their 20s and 30s." Rebecca Wood of the Alzheimer's Research Trust agreed, saying: "This research suggests that the natural decline of some of our mental abilities as we age starts much earlier than some of us might expect - in our 20s and 30s. "Understanding more about how healthy brains decline could help us understand what goes wrong in serious diseases like Alzheimer's. "Alzheimer's is not a natural part of getting old; it is a physical disease that kills brain cells, affecting tens of thousands of under 65s too. "Much more research is urgently needed if we are to offer hope to the 700,000 people in the UK who live with dementia, a currently incurable condition." http://news.bbc.co.uk/1/hi/health/7945569.stm ==== Ab jeekar kya karenge

Those were old days my friend. Most people have not even decided what they are gonna do a PhD. on by the time they reach 24. And most people do they best work after their PhD., in Math, average age of Math PhD. is probably 28. The amount of stuff you need to know to even go ANYWHERE in research in pure Math is HUGE. There is a reason Fields medal age limit is 40, and not 25. Very rarely you find field medalists younger than 30.

I can certainly feel it, but its more to do with recent stuff..if u ask me stuff from like 25 years ago, I can still remember it clearly Also, have u guys ever noticed when u r about to read a huge paragraph and ur eyes pick a word but u turned the page or read elsewhere..but u knew u saw the word somewhere...u think it migth be a mistake buts it actually there I am not sure what is it, but I get it a lot..no intention of reading something but suddenly picked a word

thats because the medal is terribly difficult to receive nowadays with most of the proofs presented previously. besides, there is a delay between the period you do the research/make the assertions that are noteworthy and the time when the same are adorned with the accolade...
