"Blanket age restrictions once you're an adult are absolute nonsense!
I've met 75 year olds who in intellect and appetite for change would put many 30 year olds to shame.
I would be in favour of assessments once past a certain age that checked competence for physical and mental aptitude but blanket bans just seem silly.
I know some hospital consultants who are 80+ at the top of their game in the field of heart expertise that are regularly saving lives and pushing the art of what's possible almost every day.
In some ways they are more eager for change and achievement as they know they have little time left and want to make it count!"
