Question Author
As an example, I know someone who is in his early fifties and lives on his own in his own house. He is a decent bloke and has a good job but is not interested in clothes, holidays, cars, women, doesn't go out much and has no hobbies. He has friends who he does socialise with occasionally and who take the micky out of him for being tight, he's not offended but he just will not spend his money. I find it rather sad that he can't bring himself to go out and enjoy life and see the world. He seems to be just existing until he dies with nobody to leave his money to. It just seems so pointless.
