I'm 55 and am not sure what the future will bring.
I won't want to just quit working cold turkey. I would go mental without having a purpose.
Perhaps working part time (veterinarian). Perhaps some volunteer humanitarian work.
I would however, love a life where if the weather was good, I had the flexibility to take time off to fish or travel.
And work when the the weather is bad.
I have gone to 4 funerals lately of people younger than me. Makes you think.
No one ever said on their death bed "I wished I worked more"
