Dynamic age calculation, the age at time of purchase

[robinaberson]

Hi!

I would like the know the age of customers at the time of purchase. For example: If a customer purchased a product two years ago I want to see their current age minus two years whenever I alter the dateslicer. 

I would like to see how many customers have a certain age at a certain time to know wheter our customerbase is getting younger or older. I want to count the amount of customers and not the amount of products. I only want to count the customers who've purchased a product in a specific timeperiod (not the whole customerbase).

Can someone please help me with this? I hope I've explained myself well enough, please tell me if it is non-sensical.
