There is a quote which goes by "Nothing to fear but fear itself". Doing startup is for the brave hearts who believe in this. To the people on sidelines it may make little sense (varying from career suicide to lottery tickets). But for the people in middle of it, they are just doing what needs to get done (albeit with lots of fighting/sacrifices and more) There is a bias in startup world towards young ( early 20's) founders. Though it looks unfavourable towards the rest (in 30's and more), it seems more humanly justifiable. Guys in the former age group could easily squeeze in 5 to 7 years of life and still do a career/life reboot if things don't work out. But, if you are in 30's with family/kids, it becomes a lot more tragic and difficult( or even worse if you did'nt even get to start a family and missed life). But even then, there are people who have ventured and found success against all odds. There is something about human will/courage/tenacity which is difficult to quantify and applied generically to people. Everyone needs to decide for themselves.
