I spent close to two years being alone a lot. I would maybe see my SO  (very talkative) or my boss (also talkative) at most for months. I would also spent weeks basically completely alone. Where the only speaking I would do would be pleasantries with gas station attendants, hotel clerks, and brief phone calls where I mostly just listened. 

My ability to form sentences began to degrade, and my ability to carry on conversations was reduced. That was over 6 years ago and I still feel the effects of that sometimes.

I notice a big difference in myself aswell in my 30s then in my 20s. I used to go out alot and meet a ton of new People and i was very social back then, had it easier to talk to new People.

Nowadays now i'm sort of stuck in the daily grind and i mostly just spend time at work and with my kids and wife i notice my social skills have gone down by alot. To a Point i sometimes wonder if that was really me in my 20s.

I feel like being social is not only something you can train but it has to be maintained or it degrades.
