I appreciate the reminders as it is upto me to react or not.
Fortunately on 2 occasions Specsavers optometrist identified a ptyrigium successfully removed. Yesterday due to extensive examination based on a suspicion of an issue a very small hole was identified in my retina this is common in old farts and all that have had heavy blow to an eye. As a kite and SUP foiler hard to wonder how this could happen

One more benefit, at my annual skin check a melanoma was identified in its early stages resulting in a positive result from a biaopsi then removal, now all good.
Is all this a con, I'll leave it to all to consider - I am ok with it.
Age creates issues but more leisure time so look after yourself when younger for a longer time on the water.
