Your body just slows down around that age, reflexes, brain etc

A bunch of reasons, reaction times go down, you have more responsibilities like family, probably burned out after playing same game for 15+ years, etc.

The dedication and motivation is not the same. Family, life becomes more important than a video game. You'll be old one day and understand too

They just dont care about the game anymore, they keep playing because its their job

it is proven that in one decade your reaction goes down 4-6 ms starting from age 24 so it doesnt matter much

There are a TON of reasons. The most obvious being reaction time, and the ability to maintain peak focus. But also older players are more likely to have other priorities that eat into their time to maintain their best form. For example, nitr0 has in recent years had to take times away from the team, including most recently just before the Major, in order to be with his wife and kids. 30-40 are usually the years people begin forming families. Also they might've lost motivation due to success, or simply burn out. As the saying goes, "victory has defeated you", success at a high level with consistency often results in a natural level of complacency.

Ton of tests and ex-athletes/professionals have often replied that it's not their reactions or speed that is often the problem. You see this a lot in professional cricket — batsman in particular, not bowlers because they often have a lot more physical injuries to manage — and sports like racing (see: Fernando Alonso). Often the biggest issue is motivation, but in esports it's also future employability. It's not as big of a deal for a professional athlete or a sportsmen to continue playing into their mid-30s because there are more pathways for them once their career ends. Esports isn't transferable in the same way, so there's more of an emphasis on people in their later 20s to make a move that shores up their lifestyle, family etc. for the next 20 years afterwards. Being a professional CS:GO player just doesn't open doors in the same way, and the esports ecosystem isn't developed enough to employ retiring professionals at the same volume that justifies them extending their careers for longer, even if they really love it.

Biggest reason is motivation

my answers r already covered but i think people tend to overemphasize reaction time compared to motivation. it's hard to play so many hours of the same game for so long, and once you slow down some teenager who's really grinding can catch up, especially if the game changes in meta or patches. otherwise i think u could make up for the reaction time with veteran knowledge, game sense, etc

In my case I have been improving over the years, better aim, way of playing, experience. I think it gets better over the years. maybe the difference is that if you play a lot, it can affect fatigue but I think that many people, at that age, lose motivation, have other responsibilities, no longer have the time or less time to play probably.

loba 33 yo god coming up on the pro scene

it will be harder to focus on practices and games

Because most of them starting to think about family and don't grind CS for 15h/a day like m0nesy

as others have already mentioned, its probably not that much about reaction time, but i would say also about other health aspects (motivation is still the biggest reason though). While being a pro you can try to compensate with diet and exercise and what not, but i don't think you can fully conserve your joints, tendons etc. While many sports are demanding in that aspect, esports are in their essence unhealthy on multiple levels. When you just sit and use your fingers in a very intense way for 10 hours a day, i dont think you can preserve all of your health. Unless you are able to maintain balance ofc, but then - id say forget about striving to be top1 without grinding as hard as possible

one word - motivation. thats all u just cant compare m0nesy and dupreeh for example

google stomach second brain

alcohol will age you faster than anythangg

forest was ace clutching against 2018 astralis at 30.

device is 27

It's not really about body aging, it's loss of motivation for many. They realize they are near 30 and either achieved something, but it was a while ago or achieved nothing. That creates logical conclusion that they will not get anything anyways and why bother.

i got 160ms average reaction time at 39 wdym

It's not easy to compete at the same level. Because, you'll have family to take care of. You have to spend more time with your kids and your wife. It's going to be hard to warm up and play for hours in front of PC like m0nesy and old s1mple. Do you know why some players keep streaming because that's the only way they can get money. A player who's single without wife getting paid 15~20k $ isn't the same as a player with wife and kids get paid 15k lol

Who gives two fucks about a practising a videogame at 30? Especially when they are already wealthy.

I'm sure it's mostly motivational things. At 30+ people tend to re-realise some things in life, discover some new pleasures (not what you think of) + established players being already wealthy and can do anything in life. So i'm sure its mostly motivation thing.

Besiddz motivation, I believe CSGO is evolving everyday and people playing from earlier times have worse base than new ones so they couldn't match it

hormones are out of balance, ur brain is out of balance, basically ur body is out of balance and u need like double to time to practise as a 16 year old.
