Expansiveness

It's only natural to note -and even lament- the things we have more trouble doing as we age, but focusing too much on scarcity often just reinforces it. 

What are the avenues we could expand (I'm not talking waistlines or paunches here) to balance the inevitable contractions?

Peter Abbott writes about being blind and developing his sense of smell. In his book,  A Guide to Scented Geraniaceae, Abbott writes that despite his blindness, by the age of seven he had learned to identify 100 different scented pelargoniums (geraniums are pelargoniums) just by their smell and texture. 

I am going to resolve right now to try to expand my abilities, a la Abbott's role model. I should be ready for spring.
