We need to balance:
1) Youth enjoys strength, fast reactions, keen eyesight
2) Youth is bedevilled by impetuosity which statistically outweighs the qualities in 1).
3) Advanced age automatically brings experience but a reduction in the qualities in 1). One can also acquire bad habits over the years.
I think the trick for older people (and others) is to take the initiative and refresh skills by taking lessons preferably by joining the IAM or RoSPA, or from a driving instructor. That way we keep up to date, improve skills and bolster confidence. Older people should recognise the value of learning, younger people might be too proud.
