My head hurts

Spent the day trying to get my head round some aspects of Photoshop - plus my hubby tried to help by giving (loaning) me his Waycom - no idea how to use it yet but hey ho!!! If I manage to produce anything I will add it to my daily collection - but today my brain hurts. When you reach my age it is soooo much more difficult to retain the information- will what I have learned today be remembered tomorrow - let’s wait and see ! B
