Placing an ad in Facebook

When you place an ad in Facebook you can see the number of people by age (based on the last 30 days usage) accessing Facebook.

I tried this out and found that Facebook stops at the age of "64".
According to this tool there are:

• 22,620 - 63 to 64 year old Facebook users in London and 50 miles
• 119,160 - 63 to 64 year old Facebook users in the UK
• 375,360 - 60 to 64 year old Facebook users in the UK

If I were to place the ad (for the suggested bidding price) it will have an estimated 97 clicks a day.
