Im about to think that my sites fonts are too small for older people.
Now i need links, hints and maybe simple way to work-around this and put into sites CSS.

Im not so good at CSS after all so help is needed, thanks!

Starting is a rather lengthy article on relative font sizes by Maxdesign, one of the leaders in Web Standards.
Easiest is to check what you are using, body? and boost it up a bit.
Relative is best as long as it doesn’ break your site if fonts made larger by the user.
One can in those cases set fixed for most of the site and relative for the main text..

I have mine at 86%, a wee bit small, but as it is percentage most know how to resize it.

On all sites I declare font size for the body like this

Then I set the font for each class that needs it in ems - 1em at this point will be roughly equal to 10pt font. Setting in ems allows users to change the font size using their browser which is good for accessability and will help you with the older people visiting your sites.

for example:

will be equivalent to 14pt and easily adjustable by the end user.
