A lot of folks have already said there's basically no such thing as too old, but I would like to add there's also no such thing as "falling behind." It can feel like starting later means you have tons of work to do to "catch up," but no one's journey is the same, and you're going to find yourself in a bad place if you start comparing yourself to other people.
Never a "too old". You just might have to work harder to "catch up" skillwise. Hayao Miyazaki and Stan Lee (before his death) are both 75+
I'm 35 and only 30 pages into a comic.
Don't let the much younger base on this particular site skew your view. You're never too old.
For some reason I though this thread would be about the age of your main character xD
But yeah, finding time to work and investing into doing it, improving and consistently working on it is more your obstacle than age is.
I started drawing when i was couple of months away from 26, not having drawn before(only in school art classes) currently couple of months away from 30. I mean it's a struggle, but if you feel this is something you were made for then the only choice is to do it.
Sorry, you're too old and the age police is coming around to your house and kneecap you.
You're going to get a lot of people telling you how it's never too late and all kind of encouraging shit, but allow me to point out a few things.
As long as you're not dead, there's no age limit to making comics. However, consider that you will likely get trounced by some 15 year old that will also get better a lot faster than you.
The older you get, the more time becomes a pressing concern. You may come to a point where you will compare yourself to others and notice how far behind you are, and you may despair at your inability to catch up because you just don't have the time. Also, you may lose touch with your audience. Your tastes will not be the same as the people reading your comic. You will not care for things they think are so hot and trendy right now.
It can be demoralising to see some kid kicking your arse and he will only get better while you have to spend enormous amounts of time and effort to move a millimetre forward.
However, if you can deal with, or even avoid, these problems, why not start your comic?
It could be far worse if you've never tried and spent the rest of your life wondering what could've been, specially when there's no entry fee.
you should check this threat to see how many creators are in Tapas that are 30+
Many people is going to tell you that the young is going to eat you and blablabla Don't listen to them, first, this is not a competition. you can be good and they can be good and we all can be happy to be creating things. And second, yes, young has it's advantages but age does it too. You had lot of things to offer, your experience, your style, no young can copy that because you have a background they don't.
So keep trying (that's the real important part) and wish you the best
I look at it from this perspective (loosely interpreted)
Possibility - which is a a basic binary logical matter of is it purely capable for anyone because of physical limitations.
Plausible - which is a statistical/reasoning matter such as there's no reason to believe it can/can't be done given your situation. So if you can find related circumstances, then yeah its plausible (if not advisable)
Practical - this is heavily a matter of afforability or ability to sacrifice other responsibilities. I argue most people struggle here. Investing in supplies, devoting time, making changes to your social life. I have a fulltime intensive career so I'm realizing its less practical to pursue art projects where uncertainty doubt and anxiety is exceptionally high while support is low (before entering my prime it was practical because it helped me prepare for my career, where now it negatively affects me)
Yes I know I over-think stuff but hopefully its useful
The following situation might be familiar to some of you.
And maybe you've already been through this process a few times, too... and it's easier said than done to get out of it
(still workin on it haha... ha... pls come hunt me down if I haven't published anything by January 2020)
But anyway!
Imagine yourself 10 years from now.
You never got started because you felt too old.
And NOW you realize that, hey, you weren't too old to get started.
You shake your first at your past self for not getting started those 10 years ago, imagining how far you could've come...
So now it's definitely too late to start... right?
And then another 5 years pass and you realize that darn it... in those 5 years you could've accomplished quite a bit.
Aaaand... so it goes.
Unless you just START, and you create something tangible.
Please take care of future you!
They say the things you regret the most are the things you never did, so...
It's the same with "waiting until you're good enough", really.
Dangerous thinking.
Don't do that.
Don't wait.
Do. 
It's the same idea that you've reached a magical age that bars you from going to school. It's never too late to take on a new skill set. In fact, it may be healthier for your brain to try to take on something new later in life. As an example, when my wife was in school, she was in a class dominated with 18-25 year olds. Except for Diane... Diane was in her 50's.
Follow Diane's lead. Follow your dreams and do what is right for you right now. Age is just a number.
That's not your age, that's insecurity.
And your age is the excuse to compare yourself to others.
And if you were the same age as those guys, then it would their art skills.
And if you had the same art skills, then it would be because they have posted more, etc.
Don't put the blame on others or on stuff you have no control over, so you can feel sorry for yourself.
Are you exhausted and need rest?
Are you surrounded by a toxic environment?
Do you feel you need some discipline?
Or to learn more art skills?
Or to make a habit out of dedicate an afternoon in the week to draw a page of your comic?
Whatever it is, do something about it. Research on whatever you need to do 
I started writing comics in my thirties. Ten years and several books later, I'm still struggling to improve distribution and increase my readership. I'm also willing to bet that most of us here, even the younger people who appear to have it made, also struggle with that.
I can only assume you are talking about this wonderful woman8.
AGE DOESN'T MATTER ┻━┻︵ (°□°)/ ︵ ┻━┻
(Unless...ya know, romance and pedo Jah Jah Jah~)
My mother is in her 40's and she texts me on Halloween of her costumes! xD So Trick or Treating doesn't have an age...why should comic-making? I think you start making a comic! Just start brainstorming ideas, look at prompts, practice drawing and find an art style that you are comfortable with and enjoy! If you can't draw/write, there are people out there willing to collab (I myself am a collaborator in a story on Wattpad. ;-
. . .Pffft. ANyways, TRY IT! Isn't that what lifes all about? Go for it! >w<
The more people I hear of doing things later in their life (i.e. not in their 20s and older) the happier I am. I think it is great to be trying out new things throughout your life. You should never stop, especially not if you have the creative bug. It seems like there is a lot of pressure from society to do amazing things when you're in your 20s, and there's nothing wrong with that! But while you're still living you still have a chance to LIVE and accomplish new things. I'm almost in my 30s and try to always keep that in mind. I don't want to ever feel like being an older age is the "end".
So basically, if you wanna make comics, make comics! And have fun!
