助詞｢も｣の意味を教えてください


「こういうこと **も** 、歳をとったらできなくなるだろうなあ」という文中の助詞｢も｣の意味を教えてください。




By using も, the speaker may be implying the activity is _not the only_ thing
he is going to miss. There are a lot of activities out there that are
gradually getting away from you as you grow old.

At least he is not thinking it to be a special case, for which は should be
used instead.
