How much of your income are you investing in the stock market?

I’m wondering, percentage wise, how much of your income you are storing in the stock market? I know this is probably dependent on age and investment strategy. Are you changing your strategy based on the current economy? I’m 25 and based on my net income (after tax) salary, i’m investing about 18.2% of my income.
