Well my son is 35 and still diving on his "Junior OW", my daughter has done some advanced dives, mostly high current so AOW isn’t all about going deep or night dives.
An equipment class is a nice addition and helps you understand your gear more. Think about first aid, rescue and o2 provider but taking AOW depends on the types of dives you are doing. Some of the greatest diving is near you and much of it might be considered advanced.
