Hi PATHURLEY54
Yes there are benefits to restarting! Provided you have no other health risks which might make restartng inadvisable at your age - and provided you continue to use transdermal HRT ie patches, then no reason why not. The old five year guoidance now no longer applied since the NICE Guidelines in 2015.
Health concerns could be - high BMI (too much fat especially), smoking, too much alcohol on regular basis, high BP, poor diet, lack of exercise, and existing cardio-vascular problems. Provided you are looking after yourself then any risks are thought to be balanced by the benefits between the ages of 60 and 70 and may even be less...
Also even if you do restart do give local oestrogen (such as Vagifem or estriol cream) some consideration as this targets oestrogen where it is needed.
