Hobby after SCI

After my injury people sometimes asked me, Do you have a hobby?  My hobbies before my injury were in the outdoors.  Today I am still asked time-to-time, do you have a hobby?   If I say, "nothing right now", I feel a bit I must have a hobby otherwise people might think I'm depressed, or no longer care about life.

I always use "reading" as my fallback hobby when a new hobby has bored me, even though I do not really feel the need to read.   Being a quadriplegia, my choices for hobbies are limited because I only enjoy a hobby I can do alone, without assistance.

Am I being stubborn minded?
