>Solution :

JavaScript is there to rescue.

HTML:

<button onclick="navigation()">Click</button>

JavaScript

<script>
function navigation(){
  var age = 40; // Not sure how you detect age
  if (age>=30 && age<=41)
      window.open("http://www.website1.com");
  else if (age>=42 && age<=99)
      window.open("http://www.website2.com");
}
</script>
