This is a very vague question but I will answer based on my belief and my investment outlook.
I believe that everyone is different and that it all comes down to personality and individual responsibilities.
Some hypotheticals to illustrate:
If I was single and had no responsibilities my risk level is off the charts- I would be willing to go 100% in because if I failed, I only have me to worry about and I know as a single individual I can endure some pretty harsh condition and will be able to work my way out.
As a married man, I still have the same personal risk level but now I have to consider my other half in the financial decisions. I can not at that point be homeless trying to work my way back like I could as a single individual because of the personal responsibility I have in that partnership.
As a married man with kids, the personal responsibilities become bigger so that further dampens your personal risk level.
Having said all that, I started investing as a young married man with children so I personally was only willing to risk that which would not leave my wife and kids homeless all my investments went down. So needless to say I did not invest as rigorously as I would have as a single person but I found a level that was conducive to my personal situation.
I hope this helps.
Good luck!
