Reasons for/against returning to activities

[isitnextyearyet1]

Just curious what makes some people more anxious than others (excluding those that are vunerable).
Speaking with sister this morning and with lockdown ending shortly we got onto children's activities. She said her son wasn't going back to his sport until maybe new year (indoor and involves contact). When chatting further she said her and hubby feel it wouldn't be safe. Son is 11 and sis and hubby late 40's. Both parents overweight and sis various underlying issues. They live in a tier 3 area with fairly high cases.

Tier 3 area, have had high rates for some time. The children returned to their activities as soon as they could and will do after Wednesday. They are not at risk and I do not believe they are likely to pass it onto us as they are primary ages. They do swimming, sport and music and I am happy for them to have that after such a crap year, it really makes them happy.
Me and DH aren’t high risk, mid 30’s, not obese, no risk factors.

Just read a notice put up about drama teachers really missing teaching classes they run in evenings outside of school and they can't understand why they are not allow run them and today they are giving out about schools not closing early for xmas incase anyone catches covid19.
So one day they complain because their drama business is affected but they dont want to be teaching their normal day job to close to xmas. Makes me laugh they complain to suit them
